Mount Gray (Vermilion Range)
Geology
Mount Gray is composed of Ottertail limestone, a sedimentary rock laid down during the Cambrian period and pushed east and over the top of younger rock during the Laramide orogeny.
History
"Mount Cambria" or "Cambria Peak" were names originally proposed in 1918 for the mountain by Charles Doolittle Walcott because it was formed entirely of Cambrian rocks. However, the mountain's name was officially adopted in 1924 by the Geographical Names Board of Canada to honor William J. Gray, a University of British Columbia student and founding member of the British Columbia Mountaineering Club who drowned in the Kootenay River on July 10, 1917, along with Charles Wales Drysdale when their raft capsized and both were swept away while working on a geologic field survey. Mount Drysdale and Mount Gray form the buttresses on opposite sides of Wolverine Pass.

Based on the Köppen climate classification, Mount Gray is located in a subarctic climate zone with cold, snowy winters, and mild summers. Temperatures can drop below −20 °C with wind chill factors below −30 °C. Precipitation runoff from the mountain drains east into tributaries of the Vermilion River, or west into tributaries of the Beaverfoot River.
