History

Mount Jimmy Simpson is named for Jimmy Simpson (1877–1972) who was a respected outfitter in the early explorations of the Canadian Rockies.^[2] Jimmy worked as a cook for Tom Wilson and learned the guide and outfitting business from Bill Peyto. In 1902, while working for Peyto, he was given the responsibility of leading James Outram's climbing expedition into the headwaters of the North Saskatchewan River and Columbia Icefield.^[4] Jimmy built a small log cabin for use with his outfitting business on the north shore of Bow Lake. It was expanded in 1937, and is now the historic Num-Ti-Jah Lodge. Jimmy continued actively guiding until the end of World War II when his son, Jimmy Simpson Junior, took over the business.^[2]

The first ascent of Mount Jimmy Simpson was made in 1897 by J. Norman Collie, George Percival, and Peter Sarbach.^[4] The mountain's name was officially adopted in 1973 by the Geographical Names Board of Canada.^[3]
