The Alaska Peninsula National Wildlife Refuge is a United States National Wildlife Refuge in southwestern Alaska whose use is regulated as an ecological-protection measure. It stretches along the southern coast of the Alaska Peninsula, between the Becharof National Wildlife Refuge on its east and the end of the peninsula at False Pass in the west. In between, however, it is broken into sections by lands of the Aniakchak National Monument and Izembek National Wildlife Refuge. The refuge is administered from offices in King Salmon, Alaska and was established to conserve Alaska Peninsula brown bears, caribou, moose, marine mammals, shorebirds, other migratory birds and fish, and to comply with treaty obligations.
Aniakchak National Monument and Preserve is a U.S. National Monument and National Preserve, consisting of the region around the Aniakchak volcano on the Aleutian Range of south-western Alaska. It has erupted at least 40 times over the last 10,000 years. The 601,294-acre (243,335 ha) monument is one of the least-visited places in the National Park System due to its remote location and difficult weather. The area was proclaimed a National Monument on December 1, 1978, and established as a National Monument and Preserve on December 2, 1980. The National Monument encompasses 137,176 acres (55,513 ha) and the preserve 464,118 acres (187,822 ha). Visitation to Aniakchak is the lowest of all areas of the U.S. National Park System, according to the NPS, with only 100 documented recreational visits in 2017. Most visitors fly into Surprise Lake inside Aniakchak Crater, but the frequent fog and other adverse weather conditions make landing in the lake difficult. It is also possible to fly into the nearby village of Port Heiden and proceed overland to the Aniakchak Crater.
The Alaska Peninsula is a peninsula extending about 497 mi (800 km) to the southwest from the mainland of Alaska and ending in the Aleutian Islands. The peninsula separates the Pacific Ocean from Bristol Bay, an arm of the Bering Sea.

The Kvichak is navigable along its entire length, and is used as a short cut by boats getting between Cook Inlet and Bristol Bay via the Lake Iliamna portage.
Birch Creek is a 150-mile (240 km) tributary of the Yukon River in the U.S. state of Alaska. Beginning at the confluence of Ptarmigan and Eagle creeks near Porcupine Dome, it flows southwest, then south under the Steese Highway and into the Steese National Conservation Area. It then turns east, then north, again passing under the Steese Highway and entering the Yukon Flats National Wildlife Refuge. Turning northwest, it ends where it splits into two distributaries, Lower Mouth Birch Creek and Upper Mouth Birch Creek, near Birch Creek, Alaska. The distributaries flow into the Yukon River at separate locations downstream of Fort Yukon.
The Mulchatna River (Dena'ina: Vałts'atnaq') is a 160-mile (260 km) tributary of the Nushagak River in the U.S. state of Alaska. Beginning at Turquoise Lake, it flows generally southwest to meet the larger river 65 miles (105 km) northeast of Dillingham. The Mulchatna's mouth is slightly south (downstream) of the village of Koliganek on the Nushagak, which continues southwest to Nushagak Bay, an arm of Bristol Bay.
The Ugashik River is a stream, 43 miles (69 km) long, on the Alaska Peninsula of the U.S. state of Alaska. It flows from headwaters near Lower Ugashik Lake and empties into Ugashik Bay, an estuary of the Bering Sea's Bristol Bay.

The Kanektok River is a 75-mile (121 km) stream in southwestern Alaska in the United States. Beginning in the Ahklun Mountains at Kagati and Pegati lakes, it flows westward into Kuskokwim Bay on the Bering Sea at the city of Quinhagak. Almost all of the river's course lies within the Togiak National Wildlife Refuge. The Quinhagak Village Corporation owns the land bordering the lowermost 17 miles (27 km) of the river.
Alaska occupies the northwestern portion of the North American continent and is bordered only by Canada on the east. It is one of two U.S. states not bordered by another state; Hawaii is the other. Alaska has more ocean coastline than all of the other U.S. states combined. About 500 miles (800 km) of Canadian territory consisting of British Columbia separate Alaska from Washington U.S. state. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S.
The Dog Salmon River is a 70-mile (110 km) tributary of the Ugashik River in the U.S. state of Alaska. Beginning on the flanks of Mount Kialagvik, it flows northwest through the Alaska Peninsula National Wildlife Refuge to meet the larger river 4 miles (6 km) southwest of Ugashik, at the head of Ugashik Bay, an arm of Bristol Bay.

Mikhail Dmitrievich Tebenkov of the Imperial Russian Navy. Exploration for placer gold occurred in the Council district area where the river valley is located, and in 1898, mining commenced. The production was substantial and ranked second only to that of Nome.

The 1958 Huslia earthquake on April 7 struck an unusual part of Alaska, near the city of Huslia, about 415 km from Fairbanks. The Ms 7.3 earthquake is one of two magnitude 7.0 or greater earthquakes recorded north of 65° latitude, the other being the 1933 Baffin Bay earthquake, and is one of the strongest earthquakes within the interior of the state. The earthquake was a result of compression of the crust due to the subduction of the Pacific Plate under the North American Plate.
