Formation of the Neoglacial Surge Moraines of the Klutlan Glacier, Yukon Territory, Canada
Abstract The Klutlan Glacier is a valley glacier 82-km long emerging from the Icefield Ranges of the St. Elias Mountains. It is one of at least 200 surging glaciers identified in western North America. During about the past 1200 yr, the glacier has deposited at its terminus a series of at least 7 su...
