UNDERGROUND WATERS. 73 
The boring is cased with 163 feet of 8-inch pipe. A small flow of 
water was obtained at a depth of 75 feet, additional supplies between 
670 and 680 feet, and the main supply at a depth of 744 feet, where 
the flow increased to 20 gallons a minute. The water-bearing sand- 
stones are in the upper part of the Casper formation. 
Pelton ranch. — On the ranch of Charles W. Pelton, in the SW. \ 
sec. 10, T. 15 N., R. 73 W., 2 miles southeast of Laramie, are two 
deep wells, one sunk in 1889 and the other in 1894. The first is 333 
feet deep and entirely in red beds. At 120 feet water was found 
which rose within 60 feet of the surface; with increased depth the 
water level rose within 7 feet of the top. The boring ended in quick- 
sand. The water is of good quality, as shown by analysis on page 
76, and it is used for irrigating an acre of garden. The second well 
is 200 yards to the north of the first, and also entirely in red beds. The 
depth is not given. The well is on a knoll, and the water rises so 
high that by means of a ditch 3 feet deep a small flow is obtained, 
which supplies a pond. 
Trabing ranch. — At the Trabing place, in the SE. \ sec. 25, T. 16 N., 
R. 74 W., 2 miles northwest of Laramie, there is a well which 
formerly afforded a good flow, but is now pumped. The depth is 
not reported. Probably its source of supply is in the red beds. 
Downie ranch. — At the Downie ranch, 3 miles west of Laramie, a 
well 400 feet deep pumps 200 gallons a minute. The main supply 
is from a depth of 395 feet. The diameter of the inner casing is 5f 
inches. Water was found also at depths of 60 to 65 feet, 190 to 200 
feet, and from 380 feet down. The water level is 20 feet below the 
surface. The following record is reported:

Also]) ranch. — A good pumping well is reported at the Alsop ranch, 
in sec 34, T. 17 N., R. 75 W. Its depth is 300 feet, and its source of 
supply is probably the sandstone of the upper part of the Montana 
group. 
u Oil well." — An unsuccessful deep boring for oil was made several 
years ago near Laramie River, at a point 3 miles wesl of I hit ton 
Lakes, in the NW. J sec. 13, T. 14 N., R. 75 W. The boring pene- 
trated about 800 feet into the Chugwater formation. The following 
record was reported from memory by Grant Lee, the driller.
