Nature
Tyndall Glacier, a valley and tidewater glacier in southeastern Alaska’s Wrangell–Saint Elias region, flows from a high basin near Mount Saint Elias into Taan Fjord. Named for physicist and glaciologist John Tyndall, it once joined neighboring glaciers in filling all of Icy Bay before their retreat opened the bay’s present form. Tyndall advanced from about A.D. 1400 to a Little Ice Age maximum before 1794, then began retreating in 1905. Its withdrawal accelerated after 1961, with major loss of length, volume, and thickness, before stabilizing after 1991 at Hoof Hill. The glacier has also served mountaineering on Mount Saint Elias and is associated with the 2015 landslide and megatsunami.
