Number 2. 
Wixp River, which in pursuing a general southeast course 
drains the entire eastern slope of the Wind River range, also 
receives from the east and north the drainage of an extensive 
mountain district, to which, as a whole, no distinctive name has yet 
been applied. To the most southeastern extension of this moun- 
tain system the name of Owl Creek range has been locally applied. 
At the lowest point, where this merges into the open and elevated - 
plains, the main stream, turning sharply to the north, loses the 
name of Wind River to assume that of the Big Horn, tributary to 
the Lower Yellowstone. Thus it happens that the same stream, 
under another name, in doubling on its upper course from south- 
east to north, receives lower down the eastern drainage of the Owl 
Creek range, and the broken mountain district to the northwest, 
through the little known Big Horn tributaries of Owl Creek, Gray 
Bull and Stinking Water. 
Our route, instead of following down the main valley, crossed 
Wind River some distance above the sharp bend above referred 
to, thence crossing a low spur of the Owl Creek range, and skirt- 
ing near the base of the high mountains to the west, passed Owl 
Creek, Gray Bull and several southern tributaries of Stinking 
ater, to ascend a main branch of the latter stream to its source
