TRIANGULATION IN UTAH, 1871-1934

J. G. STAACK, Chief Topographic Engineer

INTRODUCTION

Scope of report. This bulletin contains the results of all triangulation done in Utah by the Geological Survey of the United States 

Department of the Interior before 1936 and includes those previously 

published, 1 the work for which was done before 1915.

Precision. In general, the triangulation described in this report 

conforms to the specifications for third-order work as now defined by 

the Federal Board of Surveys and Maps. These specifications, in 

part, are as follows:

The designations for the several grades of control adopted by the Board of 

Surveys and Maps January 1], 1921, were precise, primary, secondary, and tertiary, named in order of decreasing accuracy. Prior to that time the terms primary, secondary, and tertiary had been used for the three higher grades of control. 

The nomenclature adopted in 1921 did not find wide acceptance, and therefore 

the Board in 1925 adopted the terms first ordsr, second order, third order, and 

fourth order to designate the four grades of control, first order being applied to 

the most accurate grade. This brings the nomenciature into better accord with 

general usage, and it is also easily understood without explanation by one not 

acquainted with the terms. * * *

Triangulation of the third order is ordinarily used for the immediate control of 

topographic and hydrographic surveys. Extensions of third-order triangulation 

or of third-order traverse from triangulation or traverse of a higher order should 

be made so as to control the entire area to be surveyed. Triangles of third-order 

triangulation should close with a maximum error of 10 seconds and an average error 

seldom exceeding 5 seconds. Closures in length on lines of first-order or secondorder triangulation, on lines of third-order triangulation previously adjusted, or 

on base lines, should not exceed one part in 5,000.

Instructions for conducting third-order triangulation surveys that 

were in force during the execution of the work described in this report 

are contained in Bulletin 788, entitled "Topographic instructions of 

the United States Geological Survey." Parts of those instructions 

are now obsolete. The United States Coast and Geodetic Survey, 

also, has published a description of the methods employed in triangu1 The results previously published are contained in the following publications of the Geological Survey: 

18th, 19th, 20th, and 21st Annual Eeports and Bulletins 122, 181, 216, 245, 310, 440, 496, and 644.

lation and detailed specifications and instructions for the work.2 

Some of the triangulation projects in Utah were conducted with 

more care than was given the average project, as is shown by the residuals in the original adjustments by least squares, and their results 

approached the degree of precision that is expected of second-order 

triangulation. However, as these results have been readjusted, without regard to their higher precision, in conjunction with results that 

are of average, or third-order precision, it is logical to assume that the 

average precision of all the results here published is third-order.

Instruments used. In the triangulation done before 1928, theodolites of the direction type were used. This type was equipped with a 

10-inch circle and two micrometers, each reading to 2-second divisions 

on a scale or its head. It weighed about 28 pounds without its case, 

and its tripod weighed about 19 pounds. It was well adapted to making azimuth observations and was frequently put to that use in the 

earlier years of the work, when the projects extended far from firstorder bases. Since 1928 the use of repeating instruments has gradually become common. The type now regarded as the standard is a 

transit theodolite, with which the angles are measured by the method 

of repetition. It is equipped with a 7-inch circle and two verniers, 

each reading to 10 seconds. This instrument weighs about 20 pounds 

without its case, and its tripod weighs 16 pounds.

Station marks. The Geological Survey establishes permanent marks 

at most of its occupied triangulation stations. (See pi. 1.) These 

are usually of the same form as those used for permanent marks along 

lines of leveling and transit traverse, such as bronze or aluminum tablets, iron posts, and copper bolts, but they include also drill holes, 

marks chiseled on rocks, and natural or constructed objects that can 

be so described that the exact points whose positions have been computed can be unmistakably identified.

The tablets are circular in shape, measure 3% inches in diameter 

and taper from a thickness of three-eighths of an inch at the center to 

about a quarter of an inch near the rounded edge. During a short 

period in the earlier years of the Survey's triangulation the tablets set 

were made of aluminum. The softness of this metal, however, made 

them susceptible to damage, so that aluminum as a material for tablets was soon discarded. The earliest tablets were made of bronze, and 

bronze is the material now specified for standard tablets. Each tablet is cast with a 3-inch shank extending from the center of its reverse 

side, by means of which it is cemented into place, and each bears an 

inscription on its face. The inscriptions on the tablets already placed 

differ in many .details, because of changes in design at various times. 

The face of every tablet, however, is cast with the words "U, 8,

INTRODUCTION 3

Geological Survey" 'and "Elevation above sea" and with a cross whose 

arms intersect at the center of the tablet, the point of intersection 

indicating the fiducial point for position or elevation. On the tablets 

used in the earlier work the cross is large and is the only symbol that 

appears, but on those now in use it is small and is enclosed in a triangle. On some tablets the inscription indicates that they were set 

in connection with a project in which a State or other orgarization 

cooperated. On most of those already set the inscription includes the 

warning "250 dollars fine for disturbing this mark," but the latest 

design omits this phrase and adds the sentence "For information write 

the Director, Washington, D. C."

The present practice is for the engineer who sets a triangulation 

tablet to stamp upon it with steel dies the name by which it will be 

identified in the future, choosing usually the name of some prominent 

physical feature nearby, preferably the mourtain or hill upon which 

the station is established. Then, to aid in recovering the position of 

the station in the event the station mark should be destroyed, the engineer sets at least one reference mark nearby. A special tablet is 

sometimes used for the reference mark, of the same shape and size as 

the one designed for use as a station mark. On its face is cast an 

arrow and the following inscription: "U. S. Geological Survey Reference Mark. For information write the Director, Washington, D. C." 

The reference tablet is so placed that' the arrow on its face points to 

the triangulation station to which it refers. In much of the earlier 

work of the Geological Survey, station-mark tablets were not stamped, 

nor were reference marks set, and some of the older stations were 

identified only by such natural or constructed objects as were found 

near them or could be easily carried there. In this bulletin the information given for each station includes descriptions of both its identifying mark or object and its reference mark or marks.

The tablets, whether used as station marks or reference marks, are 

cemented into holes drilled in solid rock, if this is available; if rock is 

not available they are set in the tops of reinforced concrete posts. 

Antedating the concrete posts are wrought-iron posts, to the tops of 

which are riveted bronze caps similar in design to the tablets. No 

iron posts have been set in recent years. They have proved impracticable, as they are easily disturbed or are often destroyed by rust at 

the ground level.

Another form of station mark, set only during the early triangulation, 

is a copper bolt driven into a drill hole in rock and perhaps further 

secured with lead or cement. The exposed end of the bolt bears an 

appropriate inscription, stamped upon it with steel dies.

Datum. All triangulation of the Geological Survey in Utah, with 

the exception of a few of the more recent projects, was originally
4 ' TRIANGULATION IN UTAH, 1871-1934

computed with reference to the old North American datum a or was 

expanded from local astronomic datums. In 1927, after the transcontinental triangulation had assumed the form of a net of strongclosed loops, the Coast and Geodetic Survey made a general readjustment of its first- and second-order arcs comprising the net, thereby 

establishing new geodetic coordinates defining new positions for all its 

triangulation stations. All positions determined by or based on that 

general adjustment are said to be on the North American datum of 

1927. The triangulation of the Geological Survey in Utah described 

in this bulletin has been readjusted 'consistently so that its points of 

contact with the first- and second-order triangulation of the Coast and 

Geodetic Survey shall have the same positions as those determined by 

that organization. The previously published positions, azimuths, and 

distances were revised in accordance with this readjustment, and the 

revised figures are given in this bulletin. A few of the more recent 

projects were originally computed on the North American datum of 

1927 from base stations already on that datum. These projectsr 

therefore, needed no recomputation or readjustment,

Methods of readjustment. The readjustment of the triangulation 

done by the Geological Survey in Utah to the North American datum 

of 1927 was accomplished in 1936 and 1937, the method used varying 

with the specific conditions to be met in each project.4 The triangulation was first separated into sections, or groups, each made up 

of stations originally computed on the same datum. The relation 

of each group to the adjacent groups and to the triangulation of the 

Coast and Geodetic Survey was then studied. At each point of 

contact with the triangulation of the Coast and Geodetic Survey or 

with triangulation already on the North American'datum of 1927 

corrections were derived which, if applied to the previously accepted 

position of the point, would transfer that position to the North American datum of 1927.

In any group of triangulation in which only two points of contact 

were found, these two points defined a base to which the group could 

be fitted without distorting the original adjustment or triangles. The . method of readjusting the group consisted in translating, rotating, and 

correcting the length of the base as computed on the old datum, in 

order to superimpose the base on its new datum position. Corrections

8 The term "North American datum" did not come into use until 1913. Before that time the datum on 

which the triaagulation of the Geological Survey wa? computed was known as the "United States standard 

datum." Early in 1913, however, it was decided to coordinate the triangulatiou of Canada and that of 

Mexico with the triangulation of the United States, using the "United States standard datum" to bring 

the results into agreement, and thereafter to designate this datum as <the "North' American: datum';" 

After the establishment of the "North American datum of 1927," resulting from a general readjustment of 

the triansiulation net of the Coast and Geodetic Survey, the datum in use before 1927 became familiarly 

known as the "old North American datum."

4 For a detailed description of the methods used in this readjustment see Speert, J. L., Readjustment of 

Triangulation Datum: Am. Soc. Civil Eng. Trans., vol. 103, p. 1002, 1938.
INTRODUCTION 5

consistent with the changes forced upon the base were then determined 

and applied to the positions of all stations in the group.

For a group which had three or more points of contact with triangulation already on the North American datum of 1927, the method 

of readjustment was as follows: First, a diagram was constructed 

showing the corrections to the old datum positions at the points of 

contact. Next, by a special method of graphical interpolation through 

the area between these points, appropriate corrections to the positions 

of all other stations in the group were determined. These corrections 

were then applied to the previously accepted positions so as to place 

them on the North American datum of 1927, and corrections consistent with them were applied to the azimuths and lengths of the 

lines connecting the stations in the group so adjusted.

In many of the groups, the original computations left position 

closures unreconciled at points of contact with other groups. In the 

readjustment these ties between adjacent groups have been taken into 

account, and all discrepancies at the points of contact have been 

removed.

It will be observed that the readjustment to the North American 

datum of 1927 was based, not upon a complete recomputation from 

the original field observations, but upon the application of corrections 

to the originally computed positions. Any faults that may have existed in the original computations, except those that were discovered 

before the publication of this bulletin, were therefore not removed by 

this readjustment.

Form of results. In general, positions determined by third -order 

triangulation are given in this report to hundredths of seconds of 

latitude and longitude; azimuths, to the nearest full second; and logarithms of distances, to six decimal places. An exception is made in 

the positions, azimuths, and distances in the few recent projects 

originally computed on the North American datum of 1927, which, 

since they required no readjustment, are givren as they were originally 

computed1 even though'the 'figures were carried to more decimal places 

than here specified. The additional decimal places, therefore, do not 

indicate results of higher precision but merely represent original computations. Figures given to fewer than the specified number of decimal places, however, indicate work of lower precision.

Because of the methods of readjustment used, the last digits of 

the azimuths and distances between stations as given in this report 

are dependent in general upon the new positions of the stations. This 

relation is the reverse of the usual one, in which the positions are computed from the azimuths and distances. Therefore, if any line of 

this triangulation is to be used as a base from which to expand additional third-order surveys, and if it is desired for the sake of mathematical uniformity in the computations to use figures with more decimal
6 TRIANGULATION IN UTAH, 1871-1934

places than the number here given, the following procedure is suggested: Accept as exact the given positions of the stations, and determine from them by means of an inverse computation the azimuth 

and distance between the stations to the degree of mathematical 

precision desired.

All positions, azimuths, and logarithms of distances obtained from 

the Coast and Geodetic Survey are here given as furnished by that 

organization.

Arrangement. The results of triangulation recorded in this report,, 

with the exception of some supplementary positions given in the appendix, have been divided into groups, each of which includes the 

results of a single project. These groups a,re arranged chronologically 

in the order of the dates of their corresponding projects. For each 

project there is an introductory statement including, in general, the 

following items: The name of the chief of party conducting the project; the date of the survey; the base and datum of the original computations; the designation of the report in which the results of the 

project were previously published; the points of contact with triangulation already on the North American datum of 1927, upon which the 

readjustment depends; and the relation of the project, if any, to its 

neighboring projects. Then follows a list of the stations, arranged 

alphabetically by name. Under each station name is given a description of the station, its position, and a table showing the azimuth, 

back azimuth, and distance between it and other stations.

In the appendix are listed the condensed descriptions and the 

positions of stations which were established by surveys of lower 

precision than third order or which were not sufficiently well marked 

to be of use as third-order control points.

Descriptions of stations. If any station described in this bulletin 

has been described in an earlier publication also, the description of 

that station is here reprinted as it originally appeared, except that, 

to conform with the style now in use, certain words have been abbreviated and, in a few descriptions, obvious mistakes that might be 

misleading have been corrected. These original descriptions, including the few in which minor corrections have been made, are enclosed 

in quotation marks in order that they may be easily identified. It 

has seemed desirable to add to the old descriptions notes containing 

up-to-date information obtained from maps and other sources not 

available when the original descriptions were written. These supplementary notes, if included for any station, follow the quoted 

original description. Unless otherwise stated, all distances given 

in the supplementary notes are in an air line as scaled from maps. 

If a station that has been previously described has since been recovered one or more times, then a new description combining the perti-
INTRODUCTION 7

nent information given by all the observers concerned is substituted for 

the original description. Approximate figures of elevation are given 

for each station for which they are available. Unless- otherwise 

indicated, these figures were obtained from the records of the Geological Survey, usually as determined by topographic surveys. Figures of elevation determined by the United. States Forest Service 

are indicated by "U. S. F. S.," those determined by the United States 

Coast and Geodetic Survey by "U. S. C. & G. S.," and those determined by the General Land Office by "G. L. 0."

Azimuths and distances. The azimuth and length of each line, 

formerly tabulated under the stations at both ends of the line, are now 

tabulated only at the eastern end of the line. Therefore, at any station only those sights are listed that lie toward the western half of the 

horizon; that is, the sights whose azimuths are less than 180°. An 

exception to this practice is made at stations that are near a State 

boundary, where all sights crossing the boundary line are included. 

To ascertain which sights are directed from a station into the eastern 

half of the horizon, it will be necessary, in general, to refer to the map 

accompanying the project.

Maps. The index map of Utah (fig. 1) shows the location of the 

areas covered by the various projects of triangulation in the State 

in their relation to each other. The maps of individual projects 

(figs. 2-20) show all the stations in the projects and the lines connecting them. Dashed lines on the map of any one of the projects at 

its points of contact with another project indicate observations of 

that other project that are not included in the one represented by 

the map. Lines crossing the State boundary indicate sights to stations 

of the project that lie in an adjoining State.

Personnel. The name of the engineer in charge of the field work 

for each project is given in the introductory statement that precedes 

the descriptions of stations established by that project. The original computations and adjustments were usually completed by the 

same engineer during the winter following the field season. In recent 

years the original computations for triangulation in Utah have been 

made in the office of the Pacific division of the topographic branch 

of the Geological Survey, under the supervision of H. H. Hodgeson, 

division engineer. The records contained in this bulletin have been 

readjusted and the material assembled in the section of computing of 

the topographic branch of the Geological Survey. J. L. Speert was 

in charge of the researches and computations relating to the readjustment, under the supervision of R. M. Wilson, chief of the section 

of computing, and under the general direction of J. G. Staack, chief 

topographic engineer.

PROJECTS

UINTA FOREST RESERVE, 1897-98

H. L. BALDWIN, Jr., chief of party

The stations of this project were established by an arc of triangulation starting from two stations of the United States Coast and Geodetic Survey, namely, Deseret and Mount Nebo. (See fig. 2.) The 

arc extends in a northeasterly direction into the Uinta Forest Reserve 

and then generally east along the forty-first parallel of latitude between the meridians of 109°15' and 111°15'. Some of the stations of 

this survey are in Wyoming and therefore are not described in this 

bulletin.

The results as originally computed were referred to United States 

standard (old North American) datum5 from the Deseret-Mount Nebo 

base. They were first published in two parts 6 and afterward republished as a whole.7 Other ties to first-order triangulation were later 

made at Spanish Fork Peak, Strawberry, and Lena stations. All the 

stations thus far mentioned were used to control the readjustment to 

the North American datum of 1927, which was further influenced; by 

the work of G. T. Hawkins, in 1907, and that of R. B. Robertson, Jr., 

in 1908. Hawkins' work tied in at Bridger Butte and Medicine Butte 

stations, Wyoming, and Robertson's at Lena station, Utah, and 

Richards Butte and Twin Buttes stations, Wyoming.

The projects of triangulation conducted by the Geological Survey 

that make contact with the Uinta Forest Reserve project are given 

in the following table, which includes for each project the name of the 

engineer in charge, the year, and the point or points of contact between that project and the Uinta Forest Reserve project.

NORTHEASTERN UTAH, 1909

C. F. URQUHART, chief of party

The stations of this project were established by means of a net 

of triangulation extended from three stations established by G. T, 

Hawkins in 1907, namely, Chimney and Nugget, in Wyoming, and 

Lakeview, in Utah. (See fig. 5.) This net ties also, at stations Swan 

Creek and Red Spot, to triangulation conducted by H. H. Hodgeson. 

in 1913 (Logan quadrangle project). It includes a few stations in 

Wyoming, but only those in Utah are described in this bulletin.

The triangulation was originally, computed on the United States 

standard datum, 15 and the results were published in Bulletin 496.lff

T. M. BANNON, chief of party

The survey that established the following stations, in the coal areas 

of Carbon County, started from Strawberry, Grey Head, and Indian 

Head, stations that were occupied by H. L. Baldwin, Jr., in 1897-98,.

FIGURE 6. Triangulation in eastern Utah, 1910.

and closed on United States Coast and Geodetic Survey station Patmos 

Head. (See fig. 6.) The azimuth at Patmos Head was checked by

sighting the azimuth mark established by the Coast and Geodetic 

Survey, which mark was then occupied as a station, called Patmos
EASTERN UTAH, 1910 31

Logical, and its position determined. Triangulation by C. N. Mortensen in 1934 (Duchesne quadrangle project) ties to this project at 

stations Strawberry and Grey Head.

The triangulation was originally computed on the United States 

standard (old North American) datum, 17 and the results were published in Bulletin 496. 18 Readjustment of these results to the 

North American datum of 1927 is dependent upon new positions for 

stations Strawberry and Patmos Head, as determined by the Coast 

and Geodetic Survey, and for stations Grey Head and Indian Head, 

as fixed by the readjustment of the results of Baldwin's triangulation 

(Uinta Forest Reserve project).

UINTAH COUNTY, 1913

OSCAR JONES, chief of party

This project of triangulation was extended southward from stations 

Little Mountain and Marsh Peak, established by H. L. Baldwin, Jr., 

in 1898. (See fig. 8.) C. N. Mortenson in 1934 (Duchesne quad-
UJ.NTAH COUNTY, 1913 49

rangle project) tied to stations Cone and Roosevelt of this net, and 

the Coast and Geodetic Survey in 1936 tied to station Roosevelt. 

The triangulation was originally computed on the old North 

American datum,21 and the results were published in Bulletin 644.22 

Readjustment of those results to the North American datum of 1927 

depends upon new positions for stations Little Mountain and Marsh 

Peak, as determined by the readjustment of the results of Baldwin's 

triangulation (Uinta Forest Reserve project); a new position for station 

Roosevelt, as determined by the Coast and Geodetic Survey; and a 

new position for Geological Survey station Cone, as determined by 

Mortenson from the nearby Coast and Geodetic Survey station Cone.

C. F. URQUHART, chief of party

The net of triangulation of which this project is a part lies mostly 

in western Colorado. (See fig. 9.) Only the three stations that are 

in Utah are described in this bulletin. The survey was started from 

or tied to the following United States Coast and Geodetic Survey 

stations: Tavaputs, Chiquita, Mesa, Mams Peak, and Uncompahgre, 

in Colorado, and Mount Waas and Mount Peale, in Utah. A project 

conducted by T. W. Ranta and V. J. Larsen in 1934 (Southeastern 

Utah project) ties to stations Mount Peale and Mount Waas of this 

net.

The triangulation was originally computed on the old North American datum,23 and the results were published in Bulletin 644.24 Readjustment of those results to the North American datum of 1927 

depends upon new positions for the seven stations mentioned.

The net of triangulation that includes this project is almost entirely 

in Idaho, the Utah portion of it having only one station Doubletop. 

For this reason no map of the project appears in this bulletin. The 

net was expanded from stations Henry and Woodall, which were established by the Geological Survey in 1910 and reoccupied in 1915, in 

which latter year stations bearing the same names were established 

nearby by the Coast and Geodetic Survey.

The triangulation was originally computed to refer approximately 

to the old North American datum, 25 using positions for Geological 

Survey stations Henry and Woodall based on preliminary positions 

determined by the Coast and Geodetic Survey for its stations of the 

same names. The results of the original computation were published 

in Bulletin 644. 26 The readjustment of those results to the North 

American datum of 1927 depends on new positions for Geological Survey stations Caribou, Henry, Paris, Soda, and Woodall. These were 

based, except for Soda, on new positions for the Coast and Geodetic 

Survey stations of the same names. A new position for Coast and 

Geodetic Survey station Oxford was also required.

C. F. URQUHART, chief of party

This project of triangulation was developed from United States. 

Coast and Geodetic Survey stations Deseret, Granite, Herriman, Lone 

Peak Needle, Mount Nebo, Onaqui, Salt Creek, Scipio, Spanish Fork

Peak, and Springville Peak. (See fig. 10.) Of these, stations Deseret, 

Herriman, and Mount Nebo were occupied; the others were included by 

intersection only. Two old stations that had originally been located 

by the Geological Survey by the three-point method were relocated 

by this project. They are Mammoth Peak and Bingham, located, re-

spectively, by S. S. Gannett in 1896 and R. U. Goode in 1899. Urquhart changed the name of the former from Mammoth Peak to 

Eureka, by which name this station has since been identified.

This triangulation was originally computed on the old North American datum27 in accordance with the positions determined on that 

datum by the Coast and Geodetic Survey for stations Mount Nebo and 

Deseret, and the results were published in Bulletin 644. 28 The readjustment of those results to the North American datum of 1927 depends on new positions for the ten stations of the Coast and Geodetic 

Survey cited above.

The projects conducted by the Geological Survey that make contact 

with this triangulation are given in the following table, which includes 

for each the name of the engineer in charge, the year, and the points 

of contact between that project and the Urquhart project in northern

SALT LAKE AND UTAH COUNTIES, 1922

C. F. URQUHART, chief of party

This triangulation was extended from two stations of the project 

conducted in northern Utah by the same engineer in 1915, namely, 

Coast and Geodetic Survey station Herriman and Geological Survey station Cedar Point. (See fig. 12.) It ties, also, to five other stations of that project, namely, Lake, Lehi, Lehi Temple, Murray, and 

Salt Lake City Capitol, all of which were established by the Geological Survey, and to station East Temple,32 whose position was 

determined by the Coast and Geodetic Survey, although the station 

was not occupied. Triangulation conducted by A. K. Andrews in 

1925 (Fort Douglas Military Reservation project) is tied to this 

project at stations Dry, Salt Lake City Capitol, and Lone Tree.

8J The United States Coast and Geodetic Survey lists this station as "Salt Lake City Temple, east spire."

This triangulation was originally computed on the old North American datum.33 Readjustment of the results obtained depends on 

new positions for stations Herriman and East Temple, as determined 

by the Coast and Geodetic Survey, and for stations Cedar Point, Lake, 

Lehi, Lehi Temple, and Murray, obtained by the readjustment of 

the Urquhart project in northern Utah. The published results 

appear for the first time in this bulletin.

E. R. MARTIN, chief of party

This project of triangulation was extended from Coast and Geodetic 

Survey stations Promontory and Salt Lake Northwest Base. (See 

fig. 13.) It was computed on the old North American datum.34 

Readjustment of the results to the North American datum of 1927 

depends on new positions for the base stations, as determined by the 

Coa-st and Geodetic Survey, and a new azimuth and length for the 

base. This report is the first to contain the published results of this

project.

FORT DOUGLAS MILITARY RESERVATION, 1925

A. K. ANDREWS, chief of party

This project (fig. 14) was developed from two stations established by 

C. F. Urquhart in 1922 (Salt Lake and Utah Counties project), namely, 

Dry and Lone Tree, and from station Salt Lake City Capitol, located
104 TRIANGTJLATION IN UTAH, 1871-1934

by Urquhart in 1915 (Northern Utah project) and again in 1922 (Salt 

Lake and Utah Counties project). It is made up of third- and fourthorder triangulation. The three stations named were occupied, as was 

also station Cottonwood, and the quadrilateral was adjusted as thirdorder triangulation. The remaining stations of the project were

therefore represent fourth-order triangulation.

The project was originally computed on the old North American 

datum,35 and the results were readjusted to the North American datum 

of 1927 in conjunction with the readjustment of the Salt Lake and 

Utah Counties project, conducted by Urquhart in 1922. They are

This triangulation has been computed on the North American datum 

of 1927 only. It was not adjusted by least squares, and some of the 

azimuths and distances given were obtained by averaging the azimuths and distances from two or more triangles.

The computed results of this project are published in this report

BBYCE CANYON NATIONAL PARK, 1929

H. H. HODGESON, chief of party

This net of triangulation (fig. 16) was developed from Coast and 

Geodetic Survey stations Brian and Tushar, at which points it comes 

into contact with two other projects in Utah at Brian, with Zion. National Park project, conducted by the same engineer in 1928; at Tushar 

with Iron Springs special quadrangle project, conducted by Fred McLaughlin in 1905. The chief of party was assisted in the project by 

W. R. Broaddus.

This triangulation was originally computed on the North American 

datum of 1927 and therefore requires no readjustment. In the computation the azimuths between principal stations were carried to hundredths of seconds and logarithms of distance in meters to seven decimal places. For unadjusted lines to secondary stations the azimuths 

were computed either to whole seconds or to tenths of seconds, and 

the logarithms of distance in meters to only six decimal places. The 

results have been tabulated accordingly.

Monroe 2 and Mount Catherine and Forest Service stations Nos. 6,. 8, 

M-3, and M-7, the four latter of which were located by the Coast and 

Geodetic Survey for the Forest Service.. (See fig. 17.) 

The original computation of this triangulation was based on preliminary positions for the stations above cited as referred approxiIIE°30' 111* 45'

B. H. YOAKUM and A. K. ANDREWS, chiefs of party

This project pf triangulation (fig. 18) is part of a net that is almost 

entirely in Arizona and that covers, for the most part, the area set 

aside as the Grand Canyon National Monument. The Utah part of 

this net comprises only two stations Boundary and Red Cap 

and they are therefore the only 

stations in the net described in this 

bulletin. The net was extended 

north from stations PhUlips and 

Millett around the northern end of 

the Kaibab Plateau to the two 

Utah stations, thence east and 

south and back into Arizona, where 

it closes on stations Cane and North 

Canyon.

The triangulation of the net of 

which this project is a part was adjusted rigidly within itself, irrespective of its ties to other nets. The positions were computed on a datum 

approximate to the North American datum of 1927, based on an 

arbitrarily adjusted position for station Phillips and an azimuth and 

length for the Phillips-Millett base obtained by J. T. Stewart in 1903. 

Readjustment to the North American datum of 1927 depends o;n 

adjusted positions determined by the Coast and Geodetic Survey for 

the numerous stations of the net that have been recovered by that 

organization.

The results of this project are published in this report for the first

time.

TRIANGULATION IS UTAH, 1871-1934" 

DUCHESNE QUADRANGLE, 1934

C. N. MORTENSON, chief of party

This project of triangulation (fig. 19) was extended from Coast and 

Geodetic Survey stations Cone, G. L. 0. 2, and Little, although, because of the poor visibility to the west, station Little was not occupied. 

To obtain better visibility, an auxiliary station Little No. 2 was 

established 835.24 ft. to the southwest. The project ties to Geological.

FIGURE 19. Triangulation for Duchesne quadrangle, 1934.

Survey stations Roosevelt, established by Oscar Jones in 1913 (Uintah 

County project), and Grey Head, established by H. L. Baldwin, Jr., 

in 1897-98 (Uinta Forest Reserve project). At station Grey Head it 

comes into contact, also, with triangulation done by T. M. Bannon in 

1910 (Eastern Utah project).

The original computation of this triangulation was referred approximately to the North American datum of 1927 and was based on preliminary positions for Coast and Geodetic Survey stations Cone and 

Little. Readjustment of the results to the North American datum of 

1927 depends on new positions for the three Coast and Geodetic Survey stations from which the project was extended Cone, G. L. 0. 2, 

and Little and for the following five Geological Survey stations: Altonah, Antelope, Roosevelt, and Spur, which were recovered by the 

Coast and Geodetic Survey in 1936, and Grey Head, whose new position was obtained from the readjustment of Baldwin's triangulation 

(Uinta Forest Reserve project).

SOUTHEASTERN UTAH, 1934

T. W. RANTA and V. J. LARSEN, chiefs of party

The net of triangulation designated as the Southeastern Utah 

project (fig. 20) was expanded south-westward from two stations 

of the Coast and Geodetic Survey and tied to a third; it was expanded 

from Mount Waas and Mount Peale and tied to Mount Waas Azimuth 

Mark. Of these three stations, the Coast and Geodetic Survey occupied and marked only one, Mount Waas, locating the other two 

by intersection.

The triangulation was originally computed to refer approximately

to the North American datum of 1927. Keadjustment of the results

to the datum of 1927 depends on new positions for the three stations 

mentioned and for Geological Survey stations Bears Ears, Abajo

APPENDIX

- Five triangulation projects of the Geological Survey in Utah are 

lower in accuracy than third order and for that reason have not been 

included in the main body of this bulletin. They are here grouped 

together as an appendix and are arranged chronologically according 

to the dates of the projects. Only brief descriptions of the stations 

are given, and these are assembled in tabular form. Not all the stations hi each project are included.

POWELL SURVEY, 1871-78 (in part)

A. H. THOMPSON and G. K. GILBERT, chiefs of party

This triangulation is of fourth-order accuracy and includes some of 

the stations located in Utah by the Powell Survey. Many of the 

stations located by that survey have been recovered or tied to by 

later triangulation of a higher order of accuracy, and these do not 

appear in this appendix, being included under the appropriate projects 

in the main body of the bulletin.

The original computation of this triangulation was dependent upon 

base lines measured locally and astronomic determinations of positions for the base stations. The results were published in Bulletin 

122.87 Readjustment of those results to the North American datum 

of 1927 depends on the new positions determined on that datum for 

the stations of this survey that have been tied to or recovered by 

later projects.

TRIANGULATION IN UTAH, 1871-1934 161

TINTIC MINING REGION, 1896

S. S. GANNETT, chief of party

The stations of this project that are here listed were located by 

the three-point method from Coast and Geodetic Survey stations 

Deseret, Mount Nebo, and Scipio. Station Mammoth Peak, now 

called Eureka, is not included because, although Gannett located it 

by the three-point method at about the same time that he located 

the other stations of the project, it has since been included in triangulation of a higher order of accuracy. C. F. Urquhart relocated 

this station in 1915 and changed its name to Eureka. Under that 

name it appears, with other stations of Urquhart's Northern Utah 

project, in the main body of the bulletin.

This triangulation was originally computed on the United States 

standard (old North American) datum,38 and the results were published in the Eighteenth Annual Keport.39 Readjustment of those 

results to the North American datum of 1927 requires that the positions of the stations be consistent with the new position for station 

Eureka, as determined by the readjustment of Urquhart's triangulation of 1915 (Northern Utah project).

BINGHAM SPECIAL MAP, 1899

R. U. GOODE, chief of party

The two stations of this project described in the following table were 

located by the three-point method from Coast and Geodetic Survey 

stations Deseret and Mount Nebo and Geological Survey station 

Spanish Fork Peak, which was established by H. L. Baldwin, Jr., in 

1897-98 (Uinta Forest Reserve project). Another station of the project Bingham which Goode also located by the three-point method, 

has been omitted in the table because it has been included in triangulation of a higher order of accuracy. C. F. Urquhart relocated Bingham in 1915, and it appears in the main body of the bulletin as a station 

of Urquhart's Northern Utah project.

This triangulation was originally computed on the United States 

standard (old North American) datum,40 and the results were published in the Twenty-first Annual Report.41 The readjustment of 

those results to the North American datum of 1927 depends on new 

positions, as determined by the Coast and Geodetic Survey, for stations Deseret, Mount Nebo, and Spanish Fork Peak.

E. M. DOUGLAS and PEARSON CHAPMAN, chiefs of party

Triangulation for the control of the Park City special quadrangle, 

in which the mines in the following list are situated, was extended 

from stations Wan ship and Clay ton Peak, established by H. L. Baldwin, Jr., in 1897-98 (Uinta Forest Reserve project).

This triangulation was originally computed on the United States 

standard (old North American) datum,42 and the results were published in Bulletin 216.43 The readjustment to the North American 

datum of 1927 furnishes positions of the mines which are consistent 

with the new position of Clayton Peak determined by the readjustment of Baldwin's triangulation (Uinta Forest Reserve project).

FRED MCLAUGHLIN, chief of party

The stations in the following table were located by a net of triangulation of a low order of accuracy expanded from Coast and Geodetic 

Survey stations Tushar and Milford Needle.

This triangulation was originally computed on the United States 

standard (old North American) datum,42 but was never adjusted, so 

that the positions determined for the stations were of doubtful precision. For this reason the readjustment of these positions to the 

North American datum of 1927, which requires that they be made 

consistent with the new positions for the base stations determined by 

the Coast and Geodetic Survey, leaves them still doubtful.
