- Alaska Peninsula
The Alaska Peninsula is a
peninsula extending about 800 km (500 miles) to the southwest from the mainland ofAlaska and ending in theAleutian Islands . The peninsula separates thePacific Ocean fromBristol Bay , an arm of theBering Sea .In literature (especially Russian) the term ‘Alaska Peninsula’ was used to denote the northwest part of
North America , or all of what is now the state ofAlaska with the exception of theAleutian Islands and theAlaska Panhandle .Geography
The
Aleutian Range is a highly active volcanicmountain range which runs along the entire length of the Peninsula. Within the Peninsula are several U.S. National Parks and Wildlife Refuges, including theKatmai National Park and Preserve , theAniakchak National Monument and Preserve and theBecharof National Wildlife Refuge , theAlaska Peninsula National Wildlife Refuge , and theIzembek National Wildlife Refuge .The southern side of the Alaska Peninsula is rugged and mountainous, created by the uplifting tectonic activity of the North
Pacific Plate subsiding under a western section of theNorth American Plate ; the northern side is generally flat and marshy, a result of millennia oferosion and generalseismic stability. The northern and southern shores are likewise quite different. The northernBristol Bay coastal side is generally turbid and muddy, experiences tidal extremes, and is relatively shallow; thePacific side has relatively small tidal activity and is deep and clear.Administration
All or parts of five boroughs are located on the peninsula. They are
Aleutians East Borough .Bristol Bay Borough ,Kenai Peninsula Borough ,Kodiak Island Borough , andLake and Peninsula Borough . The relatively small Bristol Bay Borough is the only one of these entirely contained in the peninsula. Lake and Peninsula Borough includes most of the peninsula's territory.Climate
In the south coast of the peninsula temperatures fluctuate between 0 ºC to -2.0 ºC (28 ºF - 32 ºf) in winter and 11º C (52 ºF) in Summer. Rainfalls are fairly steady. The climate of the south coast is only comparable to those of the
Aleutian Islands ,Iceland , andTierra del Fuego Flora and Fauna
The peninsula is devoid of trees.The Alaska Peninsula and
Bristol Bay are home to the world's largestsockeye salmon runs in large part because the Alaska Peninsula is host to so many large lakes, which are an important element in the lifecycle of "Oncorhynchus nerka", sockeye salmon. These salmon, after returning from their short life at sea, swim into the lakes and their contributing streams to spawn. Their offspring, or "fry", overwinter in the deep and food-abundant depths of these lakes until their migration to the sea in one or two years.The Alaska Peninsula is also home to some of the largest populations of native and undisturbed wildlife in the United States. Besides the famous
McNeil River andKatmai brown bear populations, large herds ofcaribou ,moose ,wolves and waterfowl inhabit the area.Demographics
Besides the communities on the "(see:
Bristol Bay )" coast, the Alaska Peninsula also is home to several well-known villages: Cold Bay, King Cove, Perryville, Chignik, Chignik Lake, Chignik Lagoon, and Port Moller. Each is primarily inhabited byAlaska Natives and each, likewise, is mostly dependent on the fishing industry for sustinence.The village of Sand Point should be included here, despite its location on Popof Island, an island of the Sumagin Islands, just off the southern coast of the Peninsula.External links
