Images of the walrus were captured over the weekend by a photographer not affiliated with the agency near Point Lay, an Inupiat Eskimo village 700 miles northwest of Anchorage and 300 miles southwest of Barrow. Many male walrus never leave the Bering Sea but females, especially mothers with pups, ride the edge of the sea ice as it moves north in summer through the Bering Strait and into the Arctic Ocean. In recent years, sea ice has receded north beyond shallow continental shelf waters and over water that exceeds 2 miles deep, beyond the diving range of an adult walrus. With this year's low summer sea ice, it's not surprising to see walrus on shore looking for a place to rest, Margaret Williams of the World Wildlife Fund in Anchorage said in a statement.
