Of streams, deposits, and other features, being immediately in front of or just beyond the outer limits of a glacier or ice sheet, and formed by or derived from glacier ice.

This photo (below) shows the proglacial environment associated with two glaciers on Bylot Island in eastern Canada. Meltwater streams can be seen flowing away from the glacier at the top of the photo. Meltwater ponded by an older moraine has formed proglacial lakes in front of the glacier at the left side of the photo. The lakes appear to be draining via a channel in the moraine near the right side of the photo. Photo by W.H. Johnson.
