Katmai National Park and Preserve is an American national park and preserve in southwest Alaska, notable for the Valley of Ten Thousand Smokes and for its brown bears. The park and preserve encompass 4,093,077 acres, which is between the sizes of Connecticut and New Jersey. Most of the national park is a designated wilderness area. The park is named after Mount Katmai, its centerpiece stratovolcano. The park is located on the Alaska Peninsula, across from Kodiak Island, with headquarters in nearby King Salmon, about 290 miles (470 km) southwest of Anchorage. The area was first designated a national monument in 1918 to protect the area around the major 1912 volcanic eruption of Novarupta, which formed the Valley of Ten Thousand Smokes, a 40-square-mile (100 km2), 100-to-700-foot-deep pyroclastic flow. The park includes as many as 18 individual volcanoes, seven of which have been active since 1900.
The Alaska Peninsula is a peninsula extending about 800 km (497 mi) 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.
Bristol Bay is the easternmost arm of the Bering Sea, at 57° to 59° North 157° to 162° West in Southwest Alaska. Bristol Bay is 400 km (250 mi) long and 290 km, (180 mi) wide at its mouth. A number of rivers flow into the bay, including the Cinder, Egegik, Igushik, Kvichak, Meshik, Nushagak, Naknek, Togiak, and Ugashik.
Naknek Lake is a lake in southern Alaska, near the base of the Alaska Peninsula. Located in Katmai National Park and Preserve, the lake is 40 miles (64 km) long and three to eight miles wide, the largest lake in the park. The lake drains west into Bristol Bay through the Naknek River. The elevation of the lake has lowered over the past 5,000 years as it has cut through a glacial moraine, separating Naknek Lake and Brooks Lake and creating Brooks Falls about 3500 years ago.
The Alagnak River is a 64-mile (103 km) tributary of the Kvichak River in the U.S. state of Alaska. It has a catchment area of approximately 1400 square mi (3600 km2). It is located in central Lake and Peninsula Borough.
The Nushagak Peninsula is an uninhabited peninsula in the U.S. state of Alaska. It is situated in the Dillingham Census Area, west of the Alaska Peninsula. The 520,000 acres (210,000 ha) byland measures 35 by 15 miles. It was named for Nushagak Bay in 1910 by the U.S. Coast and Geodetic Survey. With a large area of lakes, ponds and tidal sloughs, the peninsula contains the biggest complex of wetlands of the Togiak National Wildlife Refuge.
Becharof Wilderness is a wilderness area in the U.S. state of Alaska. Located within the Becharof National Wildlife Refuge, it comprises approximately 500,000 acres (2,000 km2) and is bordered by the Katmai Wilderness on the north. It was designated Wilderness in 1980 by the Alaska National Interest Lands Conservation Act. The region is home to a wide array of wildlife, including brown bears, salmon, caribou, and migratory birds.
Southwest Alaska is a region of the U.S. state of Alaska. The area is not exactly defined by any governmental administrative region(s); nor does it always have a clear geographic boundary.
The Egegik River is a waterway in the U.S. state of Alaska. A biological survey was conducted at the base of the Alaska Peninsula in 1902 by Wilfred Hudson Osgood, which included the Egegik River.
The Kenai National Wildlife Refuge is a 1.92-million-acre (7,770 km2) wildlife habitat preserve located on the Kenai Peninsula of Alaska, United States. It is adjacent to Kenai Fjords National Park. This refuge was created in 1941 as the Kenai National Moose Range, but in 1980 it was changed to its present status by the Alaska National Interest Lands Conservation Act. The refuge is administered from offices in Soldotna.
The Izembek National Wildlife Refuge is the smallest of the National Wildlife Refuges located in the U.S. state of Alaska. It lies on the northwest coastal side of central Aleutians East Borough. Almost all of the refuge was designated as wilderness in 1980 under the Alaska National Interest Lands Conservation Act. The refuge is administered from offices in Cold Bay.
Becharof National Wildlife Refuge is a National Wildlife Refuge in the Aleutian Range of the Alaska Peninsula of southwestern Alaska. It is adjacent to Katmai National Park and Preserve. This national wildlife refuge, which covers an area of 1,200,000 acres (4,900 km2), was established in 1980 to conserve major brown bears, salmon, migratory birds, caribou, marine birds, and mammals and to comply with treaty obligations. It lies primarily in the east-central part of Lake and Peninsula Borough, but extends eastward into the mainland portion of Kodiak Island Borough. The refuge is administered from offices in King Salmon.
Kanuti National Wildlife Refuge is a national wildlife refuge in central Alaska, United States. One of 16 refuges in Alaska, it was established in 1980 when Congress passed The Alaska National Interest Lands Conservation Act (ANILCA). At 1,640,000 acres (6,600 km2), Kanuti Refuge is about the size of the state of Delaware. Located at the Arctic Circle, the refuge is a prime example of Alaska's boreal ecosystem. It is dominated by black and white spruce, with some white birch and poplars.
The Koyukuk National Wildlife Refuge is a 3,500,000-acre (14,000 km2) conservation area in Alaska. It lies within the floodplain of the Koyukuk River, in a basin that extends from the Yukon River to the Purcell Mountains and the foothills of the Brooks Range. This region of wetlands is home to fish, waterfowl, beaver and Alaskan moose, and wooded lowlands where two species of fox, bears, wolf packs, Canadian lynx and marten prowl.
Dominated by the Ahklun Mountains in the north and the cold waters of Bristol Bay to the south, Togiak National Wildlife Refuge confronts the traveler with a kaleidoscope of landscapes. The natural forces that have shaped this land range from the violent and powerful to the geologically patient. Earthquakes and volcanoes filled the former role, and their marks can still be found, but it was the gradual advance and retreat of glacial ice that carved many of the physical features of this refuge.
The Alaska Peninsula montane taiga is a taiga and boreal forests ecoregion, located in Alaska, and defined by the World Wildlife Fund (WWF) categorization system.
The Beringia lowland tundra is a tundra ecoregion of North America, on the west coast of Alaska, mostly covered in wetland.
Sandy Lake is a lake on the Alaska Peninsula. The lake is located between the Upper Sandy River and Lower Sandy River, which drains into the Bering Sea.

Being in the foothills of the Kenai Mountains, much of the shoreline is very steep, and wooded with birch and spruce trees. The only outflow from the lake is Hidden Creek, a short, shallow creek that flows into the Kenai River just North of Skilak Lake.
