Abstract

Features of moraines and their sediments were recorded at three glaciers at the northwestern part of the island. They indicated that in these glaciers basal movement has little erosive effect. Erosion with up-transport of debris occurs mainly at the transition from steeper to lower gradients. Moraines formed there may contain basal till. In other positions moraines are formed mainly of supraglacial debris from rockfalls or wind transport. The moraine sediments are mainly waterlaid or debris flows and, in places, possibly flow till
