The Aialik Glacier is a glacier in Kenai Fjords National Park. About 15 miles from Seward, it is the largest glacier in Aialik Bay and drains the Harding Icefield. The Harding Icefield, the largest icefield contained entirely within the United States, is over 1,100 square miles and spawns some 40 glaciers. Aialik glacier is generally very stable and such massive calving events are rare. Most calving of the Aialik glacier occurs in May and June.
