Fic. 11—Pinnacle Mountain (10,062 feet = 3,067.6 m.) with Sentinel Pass 
(8,556 feet = 2,608.5 m.) on the left, near the head of Paradise Valley. A 
passing snow squall has whitened the slopes and old snow banks below the pass. 
The pinnacles are eroded from the same kind of rock as that forming the 
massive cliffs of Mount Assiniboine. Photograph by Walcott, 1916.

Fic. 12—The cliffs of Mount Hungabee at upper end of Paradise Valley, 
showing expanse of the Horseshoe Glacier. Frequent avalanches of the fresh 
fallen snow tumbled down the slopes to the fans above the glacier, as the rising 
sun loosened their hold on the rock ledges. This illustrates very clearly the 
formation of this type of glacier. Photograph by Walcott, 1916.
