Nabesna Glacier

Nabesna Glacier is a vast valley glacier in Alaska’s Wrangell Mountains, fed by heavy snowfall and about 40 tributary glaciers. Stretching about 53 miles, it is the longest valley glacier in North America and the world’s longest interior valley glacier. It flows from an icefield on the northern flanks of 14,163-foot Mount Wrangell, passes other volcanic peaks, and turns north to a terminus near the Nabesna Road. Meltwater at its lower end forms the Nabesna River. Named in 1902 by F. C. Schrader of the U.S. Geological Survey, it has long provided access into the eastern Wrangell Mountains while remaining in slow retreat since at least the early 1900s.
