till. This material melted out of the glacier, and was gradually let down on the land surface as the glacier ice melted. It is called ablation till . If the material has flowed onto adjacent glacier ice or land (fig. 2), then it is called flowtill . Till covers the bedrock surface north of the Terminal Moraine in most places except the
