The esker lies in a lowland that is largely flooded by a lake. In some places, native prairie covers the surface. Most kame or esker deposits contain so many cobblesthey are not suitable for construction purposes. Long after the glacier retreats, a drulin provides clues to the glacier's formation. When the ice melts away, the fluvial sediment is left as a long, narrow, winding ridge, which marks the course of the former subglacial, ice-walled stream.The stream may be in a crack so that it does not flow in a tunnel, and it may flow on both solid ground in places beneath the glacier and over ice in other places.
