Mount Dennis

Mount Dennis is a prominent summit in Yoho National Park near Field, British Columbia, rising sharply above the Kicking Horse River valley and the Trans-Canada Highway. First climbed in 1887 by James J. McArthur of the Dominion Land Survey, it was named in 1916 for Lieutenant-Colonel John Stoughton Dennis, who had proposed the Dominion Land Survey system in 1869, and the name was officially adopted in 1924. Formed from sedimentary rock deposited from the Precambrian to the Jurassic and later thrust eastward during the Laramide orogeny, the mountain reflects the geological forces that built the Canadian Rockies. Its severe subarctic climate has also made it a noted ice-climbing area.
