Wastage of the Klutlan Ice-Cored Moraines, Yukon Territory, Canada
Abstract A series of ice-cored Neoglacial moraines at the terminus of the Klutlan Glacier covers an area of 90 km 2 . Studies were made to determine empirically how long ice persisted in the Klutlan moraines and to develop models that can accurately predict wastage rates under current climatic condi...
