“Chushina” is a Stoney word signifying “small” and was thought to be descriptive of this ridge when members of a 1911 Alpine Club of Canada–Smithsonian Robson Expedition named this feature.
[From the crest of Phillips Mountain] a glacier slopes down for a mile and a half to the edge of the cliffs west of Snowbird Pass. It is such a fine example of a small and complete glacier from névé to foot that I think it worthy of the name Chushina.— Charles Doolittle Walcott [1850–1927]
Walcott applied his name to the glacier, but now it applies to the ridge.
“Chushina Ridge” is listed at Indigenous Geographical Names dataset as a word of undetermined language.
