Contorted Streams on the Gates Glacier
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.
