Contorted Streams on the Gates Glacier
by Allen Pope
Annual ridges and troughs (called wave ogives) are formed as the ice of the Gates Glacier (in Alaska's Wrangell Mountains) flows through a steep icefall. Down-glacier, as the ice melts, the rushing meltwater is funnelled into streams, carving ice canyons as it flows, but ultimately directed by these topographic constraints.
