SPIRIT LEVELING IN TEXAS

PART 1. WESTERN TEXAS, 1896-1935

INTRODUCTION

Scope of report. This bulletin, which for convenience is to be published in seven parts, contains the results of all spirit leveling done 

by the United States Geological Survey in Texas, including those 

heretofore published. 1 Each of the parts deals with one of seven 

sections into which the State has been divided for this purpose and 

which have been designated northeastern, southeastern, northcentral, south-central, west-central, and western Texas and the Panhandle. In each part descriptions of the points for which figures of 

elevation have been determined are listed according to the quadrangles in which the points occur. Results of spirit leveling other 

than that done by the Geological Survey have not been hi eluded.

Classification of leveling. Spirit leveling is classified according to 

the degree of refinement in the instruments and methods used and 

according to the closure errors.

First-order leveling 2 consists of leveling done with the most improved instruments, all sections being leveled twice, in opposite directions, under varying conditions. Closures are not allowed to exceed 

the amount in feet represented by the formula

0.017Vlength of section in miles.

All corrections for rod error, temperature, and unbalanced sights are 

applied, as well as the orthometric corrections for convergence toward 

the poles of level surfaces of different elevations.

Second-order leveling, according to regulations of the United States 

Geological Survey, comprises lines leveled twice with reliable instruments, though not necessarily of the most improved type. Closures 

are not allowed to exceed 0.035Vlength of section in miles.

Third-order leveling is made up of lines that are run, either with 

first-order equipment or with an engineer's wye level and rods of 

the New York type, in single-line circuits that are required to close 

within the limits, in feet, of 0.05 -^/length of circuit in miles. This 

is equivalent to 0.071 -^/length of section if the line is leveled twice.

All leveling done by the United States Geological Survey in Texas 

is of third-order accuracy except as otherwise stated.

Adjustments. The adjustment of a net of leveling begins with the 

first-order lines. Most of these lines in both the United States and 

Canada have already been combined in a general net, and the orthometric differences derived from the observed values by correction for 

the convergence of level planes toward the north have been adjusted 

to remove accidental closure errors by the mathematical method 

known as least squares. The latest adjustment of this kind was made 

in 1929 by the United States Coast and Geodetic Survey and is 

known as the "1929 general adjustment of first-order leveling." 

This adjustment included the first-order lines hi Texas, and the 

elevations thus derived are the fundamental references for elevations 

determined by second- and third-order nets. The third-order leveling 

of the United States Geological Survey in Texas has been adjusted 

by determining weighted mean elevations for new junction points 

and prorating the errors of each link. The weights are taken as the 

reciprocals of lengths of links. The third-order net has thus been 

brought into agreement with the best information available for the 

results of the fundamental first-order leveling, although the published 

figures of elevation may be changed slightly by future adjustments of 

the level net.

Benchmarks. The benchmarks used by the United States Geological 

Survey (pi. 1) are of two general classes principal and supplementary. 

Principal benchmarks are placed at more or less regular intervals 

along a level line and are established with the aim of making them as 

nearly permanent as practicable. They are usually bronze or aluminum tablets, iron posts, or copper bolts. Supplementary or auxiliary 

benchmarks are less formal in design and are placed between the 

principal benchmarks. Some of the supplementary benchmarks in 

common use are copper nails fitted with washers, spikes, and marks 

Cllt With a Chisel on rock or masonry.

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 tke Survey's leveling tke 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 set and those now being 

placed are made of bronze, and bronze is 'the material now specified
INTRODUCTION 6

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 

in 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. S. Geological Survey", a cross at the center, 

which indicates the fiducial point for position or elevation, and the 

words "Elevation above sea." On some tablets the inscription 

indicates that they were set in connection with a project in which a 

State or other organization cooperated; on some, the inscription 

includes a triangle, which signifies a located point, enclosing the 

cross at the center. Tablets bearing a triangle enclosing a cross ifiay 

be used not only as benchmarks but also as triangulation- or traversestation marks. Tfre inscription on most of the tablets already set 

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."

If the tablet is to mark a transit-traverse station, the traverseman 

stamps it with letters indicating this use of it, such as "Prim. Trav. 

Sta.", "P. T. S.", or "T. T.", as well as his own identifying letter or 

letters, the serial number of the station, and the year, using steel dies. 

If the tablet is set as a benchmark, the levelman stamps it with his 

identifying letter or letters, the serial number, and the year. He 

may at the same time stamp upon it with steel dies the elevation to 

the nearest foot, or these figures may be added later. Tablets that 

serve as benchmarks may have been set as such, or they may have 

been set to mark traverse stations. Thus many of them serve a dual 

purpose, but each has stamped upon it the date and the identifying 

designation of only that engineer who established it.

The figures of elevation that appear on a tablet are usually those 

determined by field computation only. It is sometimes found, therefore, that they do not represent the latest information. This has 

happened either because they refer to some independent datum temporarily adopted before first-order trunk lines made standard datum 

available, or because a later adjustment made in the office has rendered 

necessary an appreciable change in the figures as determined in the 

field. It is assumed that engineers and others who require accurate 

figures of elevations for the marks will use those printed in a bulletin 

such as this one, instead of accepting the stamped figures. If the 

appropriate bulletin is not conveniently accessible, a request for the 

desired information may be addressed to the Director of the United 

States Geological Survey, Washington, D. C.

The tablets, of whatever style, are cemented into holes drilled in 

solid rocks or in the walls of public buildings, bridge abutments, or 

other masonry structures. Where masonry or rock is not available,
4 SPIRIT LEVELING IN TEXAS, PART 1, WESTERN TEXAS ^

the tablets are set in the tops of reinforced concrete posts, which may * 

be either precast or mixed and molded at the selected site. The posts ^gg 

are about 8 inches square or 8 inches in diameter at the top and larger 

at the base. They are generally set so as to project about fj inches 

above ground and are made sufficiently long to reach below the frost ( ' 

line.

Antedating the concrete posts which are now constructed to hold 

the tablets, in places where masonry or rock is not available, are J 

wrought-iron posts, to whose tops are riveted bronze caps of similar ; 

design to the tablets. These iron posts measure 4 feet in length and - . 

3% inches in outer diameter and are set about 3 feet in the ground. , 

Th*e bottom of the post spreads out to a width of about 10 inches in 

order to give it a firm footing in the earth. No iron posts have been « 

set in recent years. They have proved impracticable, as they are x 

easily disturbed and are subject to rust at the ground level, which 

eventually destroys them. ' «.

The third form of principal benchmark, set only in the early leveling, is a copper bolt, designed to be wedged into a drill hole in rock or 

masonry and perhaps further secured with lead or cement. This bolt « 

measures 4 inches in length and 1 inch in diameter and has a slot at _^ 

one end into which fits a brass wedge. The wedge serves to expand 

the bottom end of the bolt, so that after the bolt has been driven to 

almost its full length into the hole, it cannot be easily removed. The 

exposed end of the bolt bears an appropriate inscription, stamped 

upon it with steel dies. This inscription is made up of the letters ,-*: 

"U S G S", the letters indicating the datum used, the abbreviated 

word "Ft", and the figures of elevation.

Supplementary benchmarks are of many kinds. One kind con- * - 

sists of a copper nail 1% inches long supplied with a copper washer 

seven-eighths of an inch in diameter through which the nail is driven 

into the root of a tree or some timber structure or cemented into rock -^ 

after bending the point. The designation "U S G S B M" is stamped 

on each washer, and on some washers the abbreviation of the name of 

the cooperating State is added. Another kind of supplementary *- 

benchmark is a chiseled square, used on the horizontal surface of a 

rock or masonry structure, or a chiseled cross, used on a vertical 

surface and, occasionally, easily described and recognized points, such - 

as doorsills and tops of hydrants. Nails, track spikes, and small 

capped iron pipes also serve as supplementary benchmarks.

- franked envelope, will be sent for use in reporting the action taken 

i; . and in recording the revised description of the mark, if any, and the

notes made in obtaining the revised elevation. 

Datum. All elevations determined by the United States Geological

Survey and those determined by the United States Coast and Geo-

- detic Survey for inland mapping are referred to mean sea level, which 

is the level that the sea would assume if the influence of winds, tides, 

and currents was eliminated. This level is not the elevation deter-

» mined from the mean of the highest and lowest tides, nor is it the 

half sum of the mean of all the high tides and the mean of all the low 

tides, which is called the half-tide level. Mean sea level is the aver-

% age height of the water, all stages of the tide being considered. It is 

determined from observations made by means of tidal gages placed 

at stations where local conditions, such as those due to long, narrow

>v bays, rivers, and like features, will not affect the height of the water. 

To obtain even approximately correct results these observations must 

extend over at least one lunar month, and if accuracy is desired they

--»- must extend over several years. At ocean stations the half-tide level

^ and the mean sea level usually differ but little. It is assumed that

there is no difference between the mean sea levels determined from

observations made in the Atlantic Ocean, the Gulf of Mexico, and

the Pacific Ocean.3

^ Location of the area. Western Texas, as the term is used in this buli» letin and as the subject of part 1 of the bulletin, is that section of the

State lying south of latitude 32° and west of longitude 103°. (See fig. 1.)

Index map. The accompanying index map of western Texas (fig. 2)

*' shows the relative position of the quadrangle areas which make up this

section; they are of two sizes 15-minute and 30-minute quadrangles.

Each of the 15-minute quadrangles measures 15 minutes in latitude 

w by 15 minutes in longitude. Each of the 30-minute quadrangles

measures 30 minutes in latitude by 30 minutes in longitude and ,is

equal in area to four 15-minute quadrangles.

* Maps of many of the quadrangles in western Texas may be purchased at 10 cents each retail or 6 cents wholesale, in lots of 50 or 

more. Prepayment is required and may be made by money order,

v payable to the Director of the United States Geological Survey, or 

in cash the exact amount, at sender's risk. Postage stamps should 

not be sent. These maps are of nearly uniform size regardless of the

* size of the areas they represent, because they are drawn on different 

scales. For some of the 15-minute quadrangles that appear on the 

index map there are as yet no corresponding maps, but these areas

accuracy except 9s otherwise stated. The figures of elevation given

for most points listed are as nearly accurate as they can be determined

at this time. In Presidio and Brewster Counties, however, much of 

the third-order leveling extends so far from the mam control of higherorder levels that the figures given should be considered as subject to 

small corrections when connected to any higher-order leveling that 

may be done in the future.
INTRODUCTION

Cooperation. The State of Texas, through the University of Texas 

Mineral Survey in 1902 and 1903 and the State Reclamation Service 

in 1909, 1910, and 1923-27, contributed financially to the work of 

mapping and leveling this section of the State.

geographers or chief topographic engineers who were in administrative charge of the topographic branch during the years when the lines 

were run. The name of the levelman who ran a particular line and 

the date when it was run immediately follow the designation of the 

route of that line and form part of the heading that precedes the 

descriptions of benchmarks. The adjustment of the third-order 

level net and the revision, correlation, and compilation of the descriptions and elevations of benchmarks, as well as the assembling of the 

lists, were done mainly by E. W. Tibbott, computer, under the supervision of R. M. Wilson, chief of the section of computing, under the 

general direction of J. G. Staack, chief topographic engineer.
