There’s a reason 18,008-foot Mount St. Elias isn’t summitted very often. The second highest peak in both Canada and the U.S., it straddles the border of Alaska and the Yukon and is known for its dramatic relief, dropping 18,000 feet from the summit to sea level, where it meets the ocean at the head of the Taan Fjord. With minimal beta and information on the peak and a near constant storm cycle blowing in from the sea, aspiring climbers and skiers are essentially left to solve the puzzle of the mountain as they go.
