Mount Blackburn

Mount Blackburn is a 16,390-foot shield volcano in Alaska’s Wrangell Mountains and the highest peak in the Wrangell volcanic field.

Wrangell Mountains: A volcanic mountain range in eastern Alaska, largely protected within Wrangell–St. Elias National Park and Preserve. Blackburn is the range’s highest summit.
Glacier: A persistent mass of ice that moves under its own weight across land. Glaciers cover much of Blackburn and carve its steep approaches.
Mountaineering: The sport and practice of climbing mountains, often involving technical terrain and expedition planning. Climbers tackle Blackburn’s remote, glaciated summit routes.
East Ridge of Mount Blackburn: A climbing route following the eastern ridge toward Mount Blackburn’s summit. It is one of the mountain’s established summit approaches.
Wrangellia: A large tectonic terrane that formed in the Pacific and later became part of western North America. The Wrangell volcanic field overlies rocks associated with the Wrangellia terrane.
Wrangell volcanic field: A broad volcanic province in eastern Alaska containing numerous volcanic centers and lava flows. Blackburn is its highest peak and one of its major volcanoes.
Icefall: A steep, broken section of a glacier where ice flows over irregular terrain. Icefalls complicate routes on Blackburn’s heavily glaciated slopes.
American Alpine Club: A United States organization that supports mountaineering, climbing education, and mountain safety. Its publications and records document climbing routes and expeditions in Alaska.
Mount Sanford: A 16,237-foot shield volcano in Alaska’s Wrangell Mountains and one of the range’s highest peaks. Sanford is a nearby high volcanic peak in the same mountain range.
Aleutian Range: A volcanic mountain chain extending across the Alaska Peninsula and Aleutian Islands. Its volcanoes belong to Alaska’s other major volcanic arc, unlike Blackburn’s Wrangell setting.
