About Mount Bona

Mount Bona is a large, ice-clad stratovolcano in the Wrangell Mountains of eastern Alaska. It is one of the higher volcanic summits in Alaska and is heavily glaciated, contributing to several major valley glaciers.

The mountain is principally of interest to experienced mountaineers because approaches cross extensive glaciers and crevassed terrain. There are no developed trails to the summit and climbs are remote, typically launched from long approach routes.

Mount Bona formed as part of the Wrangell volcanic province and is predominantly covered by ice fields that feed outlet glaciers such as the Klutlan Glacier. Its glaciated character has shaped local hydrology and terrain.

The peak sits within Wrangell-St. Elias National Park and Preserve in eastern Alaska, relatively near the Alaska-Yukon border and accessed from remote airstrips or long overland routes.
