Seward Peninsula

Seward Peninsula is a large peninsula on the western coast of Alaska, just below the Arctic Circle. About 210 miles long, it projects roughly 200 miles into the Bering Sea and is a remnant of the Bering Land Bridge that joined Siberia and Alaska during the Pleistocene.[1]

Geography

The peninsula lies between Norton Sound, the Bering Strait, the Chukchi Sea and Kotzebue Sound. Its highest point is Mount Osborn, 4,714 feet, in the Kigluaik Mountains, and other ranges include the Bendeleben, Darby and York Mountains. The Devil Mountain Lakes are described as the largest maar lakes in the world, the Lost Jim Lava Flow covers about 88 square miles, and major rivers include the Koyuk, Kuzitrin, Niukluk and Buckland.[1]

Bering Land Bridge

The peninsula is a remnant of the land bridge, roughly 1,000 miles wide, that connected Siberia and mainland Alaska during the Pleistocene Ice Age. Cape Dezhnev in Russia lies about 51 miles from Cape Prince of Wales.[1]

Communities and mining towns

Most of the peninsula lies in the Nome Census Area, with part in the Northwest Arctic Borough. Former mining towns including Council, Solomon, Candle, Haycock and Taylor no longer have year-round residents. Port Clarence was a LORAN station and Tin City is a U.S. Air Force radar station about 7 miles from Wales.[1]
