“Whirlpool River” in Alberta appears on B.C. Surveyor General Joseph William Trutch’s 1871 “Map of British Columbia to the 56th Parallel North Latitude.”
“As far as is known by the boundary survey, Whirlpool Pass has no history,” wrote boundary commissioner Arthur Oliver Wheeler in 1924. “The approach from the Alberta side, is from the main Whirlpool River valley. With regard to the name, that of Whirlpool Pass may not be very appropriate, but it has been used for lack of a better one. Perhaps, more appropriately, Athabasca Pass summit should be known by the name of Whirlpool Pass, but the former name was given in the early days of the fur trade — probably due to the fact that the Athabasca River was then the outstanding feature of this main pass over the Great Divide. It has become historical and cannot now be changed. As a substitute the name Whirlpool Pass was given by the Survey, with reference to its approach up the Main and Middle Whirlpool Valleys.”
