Whistler Mountain, the name used by residents of Alta Lake, and dating to the turn of the century, referring to the numerous whistling marmots (Marmota Caligata cascadensis) which abound in large colonies on the upper slopes. Dr. Neal Carter's 1924 map (35-H, Geographic Div) labels "London (Whistler) Mtn" and his 1927 letter identifies "Whistler Mtn-also Mt London..." (file G.1.28). However, the mountain was labelled just "London Mtn" on the 1928 Garibaldi Park Map published by the newly-formed Garibaldi Park Board. "London Mountain" undoubtedly refers to the nearby London mineral claim, staked for Frederick James Proctor of the London & British North America Mining Co. of Vancouver, in 1903. (files G.1.30 and P.1.51).
