oeen put down, with various results. More or less definite reports con- 
cerning them are here presented: 
At Rock Creek post-office a 6-inch drill hole 300 feet deep failed to 
reach water under sufficient pressure to cause it to rise to the surface. 
Water stands about 10 feet below the top of the well and is pumped. 
The well is imperfectly cased, and no adequate tests of the pressure of 
the water have been made. It seems probable that if this well should' 
be properly eased a surface flow r would result. 
Near Dry Creek, about 1<) miles east of Rock Creek post-office, and 
about one-half mile from the foothills to the south, a drill hole, situ- 
ated near a warm spring, is reported to have a depth of between 200 
and 300 feet, and to discharge a small amount of warm water. Judg- 
ing from reports, this well is on the Snake River Plains, w r here the 
surface rock is basalt. 
About 1 miles west of Rock Creek post-office, on the McMullen 
ranch, near the border of the Snake River Plains and adjacent to the 
Rock Creek Hills, a 6-inch well, 50 feet deep, is reported to discharge 
a small stream of warm water. About 10 miles farther west what 
is known as Wild Horse well is said to be 75 feet deep and to furnish 
a small supply of warm water. 
Of the several flowing wells in and about the Rock Creek Hills, I 
was enabled to visit only the three on Rock Creek, but the success of 
these and the surface discharge from the others referred to is evidence 
that water exists under pressure beneath a region many square miles 
in area. Whether or not there is a continuous water-charged stratum 
in this region at a moderate depth beneath the surface is not demon- 
strated, but the facts in hand are such as to justify a thorough test. 
It is highly desirable that the well at Rock Creek post-office and also 
the wells east and west of that locality should be continued downward 
several hundred or possibly 1,000 feet, in order to determine positively 
the actual conditions. 
There is a vast amount of fine land about the Rock Creek Hills, and 
the indications are that artesian water can be had for the irrigation of 
a considerable portion of it. 
UNSUCCESSFUL WELLS. 
In addition to those places at which the flowing wells briefly described 
on the preceding pages were obtained, attempts have been made to 
obtain flowing wells at various other localities, principally, so far as I 
am aware, on the northern border of the Snake River Plains. Thus 
far these attempts have all been unsuccessful. 
At Shoshone, a well was drilled in 1890, with the hope of obtaining 
flowing water for town purposes, to a depth of 280 feet, all in lava, 
but no water was reached.
