The mountain was named after Sir William Edmond Logan, a Canadian geologist and founder of the Geological Survey of Canada (GSC).

Mount Logan is located within Kluane National Park Reserve[6] in southwestern Yukon, less than 40 km (25 mi) north of the Yukon–Alaska border.

Although many shield volcanoes are much larger in size and mass, Mount Logan is believed to have the largest base circumference of any non-volcanic mountain on Earth,[7] including a massif with eleven peaks over 5,000 m (16,000 ft).

An international team of Canadian, British and American climbers was assembled the following year, initially planning an attempt in 1924 but forced by funding and preparation delays to postpone the trip until 1925.

In the early evening of June 23, 1925, Albert H. MacCarthy (leader), H.F. Lambart, Allen Carpé, Norman H. Read, W.W. Foster, and Andy Taylor stood on top for the first time.

[30][31] It had taken them 65 days to approach the mountain from the nearest town (McCarthy across the border in Alaska), reach the summit, and return, with all climbers intact, although some of them suffered severe frostbite.
