Seward Peninsula

Seward Peninsula

The Seward Peninsula is a large peninsula on the western coast of the U.S. state of Alaska. It projects about convert|320|km|mi|-1|sp=us into the Bering Sea between Norton Sound, the Bering Strait, the Chukchi Sea, and Kotzebue Sound, just below the Arctic Circle. The entire peninsula is about convert|330|km|mi|-1|sp=us long and convert|145|km|mi|0|abbr=on-convert|225|km|mi|0|abbr=on wide.

The Seward Peninsula was once part of the Bering land bridge, a roughly thousand mile wide swath of land connecting Siberia with mainland Alaska during the Pleistocene Ice Age. This land bridge aided in the migration of humans, as well as plant and animal species from Asia to North America. Archeological discoveries throughout the Seward Peninsula show proof that Inupiat Eskimos have been living in the region for thousands of years. Excavations at sites such as the Trail Creek Caves and Cape Espenberg in the Bering Land Bridge National Preserve as well as Cape Denbigh to the south have provided insight into the timeline of prehistorical migrations from Asia to the Seward Peninsula.

Other locations on the Seward Peninsula include the mining towns of Council, Solomon, Candle, Haycock and Taylor. While still frequented by locals of neighboring communities, there are no longer year round residents in these locations. There is a United States Coast Guard LORAN station at Port Clarence. The U.S. Air Force operates a radar station at the "Tin City" site, convert|7|mi|km|0 southeast of Wales.


The Seward Peninsula has several distinct geologic features. The Devil Mountain Lakes on the northern portion of the peninsula are the largest maar lakes in the world. They were formed over 21,000 years ago as the result of an underground steam explosion. [Rozell, Ned. [ Volcanoes, permafrost, earthquakes shape Alaska] Alaska Science Forum.] The Killeak Lakes and White Fish Lake are also volcanic maar lakes of notable size on the northern Seward Peninsula. Four mountain ranges line the southern side of the peninsula, the most prominent being the Kigluaik (or Sawtooth) Mountains. The highest point in the range and the peninsula is the peak of convert|4714|ft|m|0|sing=on Mount Osborn. Other mountain ranges on the Seward Peninsula include the Bendeleben Mountains, Darby Mountains, and York Mountains. The Lost Jim Lava Flow north of Kuzitrin Lake is a lava field formed roughly 1,000 to 2,000 years ago, which covers roughly convert|88|sqmi|km2|0.Several geothermal hot springs are located throughout the peninsula, including Serpentine Hot Springs, Pilgrim Hot Springs, Granite Mountain, Elim, Clear Creek and Lava Creek.

The Seward Peninsula has several rivers. The largest include the Koyuk, Kuzitrin, Niukluk, Fish, Tubuktilik, Kiwalik, Buckland and Agiupuk Rivers. These play a vital role in the subsistence lifestyles of many peninsula residents and ease travel, hunting, and fishing. Most peninsula rivers have at least a small yearly run of several varieties of salmon, as well as Dolly Varden, Arctic Grayling, whitefish of various species, Northern Pike, and Burbot. Most rivers on the Seward Peninsula freeze in mid-October; spring break-up usually occurs in mid- to late May.

Cape Prince of Wales, the westernmost point on the mainland of the Americas, is on the western tip. The cape is only convert|52|mi|km|0 from Cape Dezhnev, the closest point on the Russian mainland.

The peninsula was named after William H. Seward, the United States Secretary of State who negotiated the Purchase of Alaska from Russia in 1867.
