Wrangel Island was declared a federally managed nature sanctuary in 1976, and it remains one of Russia’s coldest, remotest pieces of protected wilderness. The 2,900-square-mile island is a haven for wildlife, frozen in space and time. Despite the severity of its climate, and in many ways because of it, Wrangel boasts an astonishing abundance of life. The island is the world’s largest denning ground for polar bears. Wrangel also supports the largest population of Pacific walruses, and the only snow goose nesting colony in Asia. It is home to snowy owls, muskoxen, arctic foxes, and reindeer as well as massive populations of lemmings and seabirds. Wrangel Island is located in Arctic Ocean, between the Chukchi Sea and East Siberian Sea.
