Port-Alsworth is a small community located in south-central Alaska's Lake and Peninsula Borough. As of the 2010 census, the population was 159 residents. Port Alsworth was founded in 1950 by Babe and Mary Alsworth. Babe Alsworth was a missionary and bush pilot and Mary became the town's first postmistress. This region (Lake and Peninsula Borough) is the second least densely populated place in the United States, with only the Yukon-Koyukuk area being less populated. There are several national protected areas near Port Alsworth; the Alagnak Wild River, Alaska Maritime National Wildlife Refuge, Alaska Peninsula National Wildlife Refuge, Aniakchak National Monument and Preserve, Becharof National Wildlife Refuge, Katmai National Park and Preserve, Lake Clark National Park and Preserve and the Lake Clark Wilderness. The Alagnak River is a 79-mile long river that is one of the best sport fishing rivers in Alaska. The river is can also be used for canoeing and rafting, although the ravine is dangerous for inexperienced rafters, especially during high water. Also near Port Alsworth is Lake Clark Wilderness, which has been called the "essence of Alaska," for its' variety of features not found in other parts of the state: the junction of three mountain ranges, two active volcanoes, a coastline with rainforests on the east (similar to southeast Alaska), a plateau with tundra on the west (similar to Arctic Alaska), and crystal clear lakes. No roads lead into this park, and it can only be reached by aircraft or floatplanes. It's well worth the visit, though, if you can make it.

Port Alsworth Weather & Climate

South-central Alaska has a four-season climate that is tempered by the relatively warm ocean waters to the south and the Alaska Range to the north. This protects it from the very cold temperatures common to interior Alaska. Summer temperatures rise into the 70s, with occasional highs in the 80s, however night time readings may fall into the 40s. Winter temperatures average around 6.4 degrees F. minimum, but may fall to 20 degrees below zero and rise above freezing later on. September is the wettest month of the year. Summertime weather is typically cloudy, although sunny skies are not uncommon. This region receives about 50 inches of snowfall in the winter. There are two glaciers in the area, the Matanuska Glacier and the Knik Glacier. Wind blows off of these glaciers and funnels into the region.
