Wheeler’s map Mount Robson 1912 [as Trios Pk.]

During the 1911 Alpine Club of Canada–Smithsonian Robson Expedition, the exploratory party of Arthur Oliver Wheeler [1860–1945] climbed “the high rock buttresses that stood out prominently behind our camp to the northwest. The station was a low one, but commanded fine views up the valley of Moose River and of the valleys surrounding the Colonel. The station was named ‘Trios’ on account of its shape.”

Topographic Survey of Canada advises “the origin of the name is obviously that it has three peaks.”
