In Wind Cave Canyon, where water-hole number 
10 is marked, is a beautiful park about half a mile in 
extent and surrounded on all sides by pine-clad and 
rocky country rising 200 feet. On account of the strong 
sunlight the photograph (No. 1) gives this valley the 
appearance of being barren, but it is covered with good 
erazing, and is an ideal protection from storms. 
The entire Reserve contains ravines, gullies and 
draws that afford protection from storms and are supplied 
with good grass of one kind or another. 
For a distance of about two miles south and a mile 
east of the northwest corner, and about a mile north and 
west of the southeast corner, the rock lies near and crops 
above the surface of the ground. The altitude of Wind 
Cave is 4,100 feet. 
WATER 
The Reserve this year contained less water than 
ever has been known before. I would suggest that 
the society arrange with some one,—preferably Mr. 
W. A. Rankin, late superintendent of the Park, who 
visited the watering places with me,—to watch the 
water during the remainder of the summer, and report 
on its condition. He might be supplied with a copy 
of map B, that his work and report may be simplified. 
In October, 1906, Prof. Cleophas O’Harra, of the 
South Dakota School of Mines, was detailed by the 
Interior Department to examine the water supply at 
the Park. His object was to supply the buildings at 
Wind Cave with pure water from some near-by point. 
An artesian well was suggested, but Professor O’Harra 
found that owing to the depth of the lime and sandstone 
it would be impossible, with the small amount appro- 
priated for such use, to drill deep enough to secure water. 
It was said that several years ago private parties 
attempted to strike water about the center of the Park, 
but when the drill reached a depth of about nine hundred 
feet 1t dropped into the cave, and operations ceased. 
These facts must not be accepted as unfavorable to 
the region as a game reserve, however, for after a long
