KESULTS OF SPIRIT LEVELING IN COLORADO, 1896 TO

1910, INCLUSIVE.

R. B. MARSHALL, Chief Geographer.

INTRODUCTION.

Scope of the work. All results of spirit leveling in Colorado previously published by the United States Geological Survey and all 

the results of later work are included in this report, rearranged by 

quadrangles. Nearly all elevations are based on preliminary 1911 

adjustment heights of bench marks along the precise level lines of the 

Coast and Geodetic Survey from Colorado Springs, Colo., via Denver to Laramie, Wyo., and on Coast and Geodetic Survey precise 

bench marks near Albuquerque, N. Mex., connection having been 

made by precise and primary leveling of the United States Geological Survey.

Personnel. The field work from 1896 to 1906, inclusive, was done 

under the general direction of E. M. Douglas, geographer; that for 

1907 to 1909, inclusive, under E. C. Barnard, geographer; and the 

later work under Sledge Tat.um, geographer, under the general direction of R. B. Marshall, chief geographer. The names of the various levelmen are given in the introduction to each list. The office 

work of computation, adjustment, and preparation of lists was done 

mainly by S. S. Gannett, geographer, and D. H. Baldwin, topographer, and since 1907 under the general direction of E. M. Douglas, 

geographer.

Classification. The elevations are classified as precise or primary, 

according to the methods employed in their determination. For precise-level lines instruments and rods of the highest grade are used, 

each line is run in both forward and backward directions, and every 

precaution is taken to guard against error. The allowable divergence 

between the forward and the backward lines in feet is represented by 

the formula 0.017VD, in which D is the distance in miles between 

bench marks. For primary lines standard Y-levels are used; lines 

are run in circuits or are closed on precise lines, with an allowable

5
SPIRIT LEVELING IN COLORADO, 1896 TO 1910.

closing error in feet represented by 0.05 VDj in which D is the length 

of the circuit in miles, sufficient care being given to the work to maintain this standard. For levels of both classes careful office adjustments are made, the small outstanding errors being distributed over 

the lines. Orthometric corrections have been applied in determining 

the following elevations.

Bench marks. The standard bench marks are of two forms. The 

first form is a circular bronze or aluminum tablet (C and E, PI. I), 

3£ inches in diameter and one-fourth inch thick, having a 3-inch 

stem, which is cemented in a drill hole in solid rock in the wall of 

some public building, a bridge abutment, or other substantial masonry 

structure. The second form (F, PI. I), used where masonry or rock 

is not available, consists of a hollow wrought-iron post 3^ inches in 

outer diameter and 4 feet in length after being split at the bottom 

and expanded to a width of 10 inches in order to give a firm bearing 

on the earth. A bronze or aluminum-bronze cap is riveted over the 

top of the post, which is set about 3 feet in the ground. A third 

style of bench mark with abbreviated lettering (B and Z>, PI. I), is 

used for unimportant points. This consists of a special copper nail, 

1^ inches in length, driven through a copper washer seven-eighths of 

an inch in diameter.

The tablets, as well as the caps on the iron posts, are appropriately 

lettered, and State cooperation is indicated by the addition of the 

State name (£, PI. I).

The numbers stamped on the bench marks described in the following pages represent the elevations to the nearest foot, as determined 

by the levelman. These numbers are stamped with ^-inch steel 

dies on the tablets or post caps, to the left of the word " feet." The

office adjustment of the notes and the reduction to mean sea level 

datum may so change. some of the figures that the original markings 

are 1 or 2 feet in error. It is assumed that engineers and others who 

have occasion to use the bench-mark elevations will apply to the 

Director of the United States Geological Survey at Washington, 

D. C., for the adjusted values, and will use the markings as identification numbers only.

Datum. All United States Geological Survey elevations are referred to mean sea level, which is the level that the sea would assume 

if the influence of tides and winds were eliminated. This level is not 

the elevation determined from the mean of the highest and the 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 average 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 long 

narrow bays, rivers, and like features will not affect the height of
INTRODUCTION.

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 level as 

 determined from observations in the Atlantic Ocean, the Gulf of 

Mexico, or the Pacific Ocean.

The connection with tidal stations for bench* marks in certain areas 

that lie at some distance from the seacoast is still uncertain, and this 

fact is indicated by the addition of a letter or word to the right of 

the word " Datum " on tablets or posts. For such areas corrections of 

published results will be made from time to time as the precise-level 

lines of the United States Geological Survey or other Government 

organizations are extended.

or partly in Colorado, have been published by the United States 

Geological Survey up to May 6, 1911. They may be obtained (except as noted) for 5 cents each, or $3 a hundred, on application to

PRIMARY LEVELING.

Denver, Greeley, loveland, and Niwot quadrangles.

ARAPAHOE, BOULDER, AND >VELD COUNTIES.

The elevations in- the following list are based on the elevation of 

the top of the lower pedestal at the southeast corner of the steps of 

the Colorado State capitol, at Denver. The point is marked by the 

letters " U.S.B.M." cut in the top of a granite block. The elevation 

is obtained from the Coast and Geodetic Surv.ev transcontinental line 

of leveling, and is now accepted as 5,278.255 feet, according to approximate adjustment in 1911.

Leveling was done in all four quadrangles in 1897 by Thomas Winsor, and in 1899 by E. W. Glafcke and A. E. Franklin. Additional 

work was done in the Loveland and Niwot quadrangles in 1902 by 

F. M. Taylor.

DENVER QUADRANGLE. 

Bench marks established at Denver.

NOTE. The first five elevations result directly from precise leveling of the Coast and Geodetic Survey, as described in their report 

for 1903, Appendix No. 3. The tablets were set by the United 

States Geological Survey.

LAKTMEB COUNTY.

The elevations in the following list are based on the elevation of the

lower pedestal at the southeast corner of the steps of the Colorado 

State capitol, at Denver. The elevation is obtained from the Coast 

and Geodetic Survey transcontinental line of levels and is accepted 

as 5,278.255 by the approximate adjustment of 1911.

The leveling was done in 1905 by G. A. Joslin.

The line from Belleview to Livermore was run as a precise line. 

The circuit from Forks Hotel via Alvord and return to Forks Hotel 

was a single line using the same level. The balance of level lines were 

run with a Y level and New York rods.

The elevations in the following list are determined by primary 

leveling extended from Colorado Springs. The lines southeast from 

Pueblo were originally based upon an elevation at Pueblo determined 

from leveling of the Denver & Rio Grande Railroad, corrected to 

accord with the 1906 accepted height of a bench mark at Colorado 

Springs. The values here given, however, result from a double

results of a line extended from Salt Lake, Utah, along the Denver & 

Bio Grande Eailroad to Grand Junction, Colo. Corrections have 

been applied as in precise leveling, including orthometric corrections 

and adjustment of closure error of about 1 foot. The elevations 

adopted at Salt Lake and Grand Junction were determined in accordance with a preliminary adjustment by the Coast and Geodetic 

Survey in 1911.

bench marks at Montrose, Colo., established by precise leveling of 

the United States Geological Survey, and at Albuquerque, N. Mex., 

established by precise leveling of the Coast and Geodetic Survey, 

the connection being made by the primary level net.

The leveling in the Creede quadrangle was done in 1904 by J. E. 

Chapson; that in the San Cristobal quadrangle in 1899 by T. Winsor and in 1904 by Chapson; that in the Silverton quadrangle in 

1899 by Winsor and- in 1901 by Chester Irvine; that in the Needle 

Mountains quadrangle in .1898 by T. Winsor and in 1900 by J. P.

Beach, in 1897 by A. L. Fellows, and in 1898 by Winsor; and that

The considerable error in stamped elevations is due to.the assumed 

datums upon which the field work was done.
