Part 3: Glaciers - Depositional Features The term glacial drift is applied to all sediment of glacial
origins, regardless of how, where, or in what way it was deposited. Drift comes in two types; (1)
till, which is unsorted sediment that is deposited directly by the ice, (2) outwash (a.k.a. stratified
drift), which is the drift that has been sorted and deposited by the flow of glacial meltwaters. The
most widespread depositional features associated with glaciers are moraines, which are ridges of
glacial till that form along the margins of the ice. Terminal (end) moraines are a ridge of till that
forms at the terminus of the glacier, where the ice front is stationary. End moraines mark the
farthest advance of the glacial ice. Another type of moraine is a recessional moraine that forms
when the ice becomes stationary for a time during a period of retreat. Ground moraines represent
a layer of till that is deposited by the base of the retreating ice. There are several other
depositional features listed below, many are illustrated in Figure 11. Review your class notes and
write out a definition for each depositional feature: - Kettle Lakes: - Kame: - Drumlin: - Esker:
