 aggregate 15,360 acres, belong to the reserve, the southern portion lying within 

 the boundaries of Yellowstone National Park. The eastern part consists of the 

 •central, or canyon, portion of Hell Roaring Creek Basin, here a narrow valley, 200 

 to 300 3'ards wide at the bottom, sunk 1,500 to 2,000 feet below the summits of the 

 inclosing ridges. The eastern wall rises steep and rock}-, with long talus slopes

 of coarse, heavy, bowlder drift.
