The geologist behind the mountain
The name belonged to Sir William E. Logan, the geologist who founded the Geological Survey of Canada. The mountain stands 5,959 meters in Yukon's Kluane National Park and Reserve, on the traditional territories of the Kluane and White River First Nations.
Even its height has moved. Albert H. MacCarthy led the first ascents in 1925. Those climbers put the high point at 6,050 meters, which a later resurvey corrected downward.
