“Clairvaux Mountain” adopted in Place Names of Alberta, 1928. Form of name changed to Mount Clairvaux in 1976, as originally labelled on BC-Alberta Boundary sheet 29, 1917.
Intended to express its situation at the head of a “clear valley.”

In 1911, Arthur Oliver Wheeler [1860–1945] named this mountain Little Grizzly Peak “on account of its resemblance, on a small scale, to Mount Grizzly in the Selkirks.” Cinnamon is a coloration of the grizzly bear.

The well-known Cinnamon family of Robson Valley did not arrive in the area until the 1950s.

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,” wrote Charles Doolittle Walcott [1850–1927] after his 1912 reconnaissance of the Robson region.

The name was adopted in 1962 as submitted by mountaineer Gertrude Smith. “This is a ridge with 5 peaks … chilkst is the Shuswap word for 5.”

The name “Mount Chamberlin” was suggested by the 1949 mountaineering party of Sterling Brown Hendricks [1902–1981] and Andrew John Kauffman [1920–2002]. “Chamberlin Peak” was adopted in 1963 by the British Columbia Geographical Names Office, as there was already a Mount Chamberlin, named in 1917 for the unrelated Edson Chamberlin, about 50 kilometres to the north near Mount Robson.

The name was submitted by Alpine Club of Canada [1906–] to recognize Rollin T. Chamberlin (1881–1948), geologist and mountaineer. Chamberlin ascended Tête Creek in 1924, and made several climbs in that area of the Cariboo Mountains, including the first ascent of Mount Sir Wilfrid Laurier (called Mount Titan at the time). Chamberlin, a professor of geology at the University of Chicago, was author of The Gases in Rocks.
