Elgygytgyn Lake

Lake Elgygytgyn fills a nearly circular crater in the highlands of central Chukotka. Formed by a meteorite impact millions of years ago, the deep lake is surrounded by tundra and a rim of hills. Numerous small streams enter it, but only the Enmyvaam flows out, cutting through the southeastern rim. Ice covers the lake for most of the year, and its name is associated with enduring ice.
