The Knife Creek Glaciers of Katmai National Monument, Alaska
Abstract A group of previously unmapped glaciers on the slopes of Trident and Katmai Volcanoes, southwestern Alaska, was studied for information on the abnormal regimen produced by effects of the 1912 eruption of Mount Katmai. During the eruption an area of 5 square miles (13 km. 2 ) of the summit a...
