The mountain was named by George M. Dawson in 1894 for Sir John Henry Lefroy (1817–1890), an astronomer who had traveled over 8,800 kilometres (5,470 mi) in Canada's north between 1842 and 1844 making meteorological and magnetic observations.[1]

The mountain is the site of the first fatal climbing accident in Canada. In 1896 during a failed summit bid, Philip Stanley Abbot slipped on rocks after just coming off an icy section and plummeted down the rock face to his death.[1]

The first successful ascent was made in 1897 by J. Norman Collie, Arthur Michael, H. Dixon; Charles Fay, Peter Sarbach, R. Vanderlip, C. Noyes, Charles Thompson, and H. Parker.[2]

A prominent painting by Canadian Group of 7 artist Lawren Harris, was painted at this site.[4]

Geology

Mount Lefroy is composed of sedimentary rock laid down during the Cambrian period. Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.[5]

Climate

Based on the Köppen climate classification, Mount Lefroy is located in a subarctic climate with cold, snowy winters, and mild summers.[6] Temperatures can drop below −20 °C with wind chill factors below −30 °C.
