The road rises up onto a ridge in the distance. This ridge represents an end moraine: an accumulation of till and outwash materials formed at the margin of continental ice as the margin stabilized in position - probably over a period of many years.

Geologists use moraines to map ice margin positions through time. This moraine, located west of Kathryn, N.D., marks the position of a small re-advance of ice. From this view, the ice margin itself would have been on the distant side of this end moraine.
