Mount Turner, also known as Boundary Peak 162, is an 8,661+ foot (2,640+ meter) glaciated mountain summit located in the Fairweather Range of the Saint Elias Mountains, on the Canada–United States border between southeast Alaska and British Columbia. The peak is situated on the shared boundary of Glacier Bay National Park with Tatshenshini-Alsek Provincial Park, 80NaN0 west of Tarr Inlet, and 4.40NaN0 southwest of Mount Forde, which is the nearest peak. Turner is the highest point on the divide which separates Ferris Glacier from Margerie Glacier. The mountain's name was officially adopted by the Geographical Names Board of Canada on March 31, 1924.[3] The mountain was named for George Turner (1850–1932), one of the US members of the 1903 Alaska Boundary Tribunal.
Based on the Köppen climate classification, Mount Turner has a subarctic climate with cold, snowy winters, and mild summers.[4] Weather systems coming off the Gulf of Alaska are forced upwards by the mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports small hanging glaciers on its slopes as well as the larger Margerie Glacier to the south and Ferris Glacier to the north. Precipitation runoff and meltwater from its glaciers drains into Glacier Bay Basin.
