Mount Assiniboine, also known as Assiniboine Mountain, is a pyramidal peak mountain located on the Great Divide, on the British Columbia/Alberta border in Canada.At 3,618 m it is the highest peak in the Southern Continental Ranges of the Canadian Rockies. Mt. Assiniboine rises nearly 1,525 m above Lake Magog. Because of its resemblance to the Matterhorn in the Alps, it is nicknamed the "Matterhorn of the Rockies”. Mt. Assiniboine was named by George M. Dawson in 1885. When Dawson saw Mt. Assiniboine from Copper Mountain, he saw a plume of clouds trailing away from the top. This reminded him of the plumes of smoke emanating from the teepees of Assiniboine Indians.
