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.
Grand Coulee is an ancient river bed in the U.S. state of Washington. This National Natural Landmark stretches for about 60 miles (100 km) southwest from Grand Coulee Dam to Soap Lake, being bisected by Dry Falls into the Upper and Lower Grand Coulee.
The Channeled Scablands are a relatively barren and soil-free region of interconnected relict and dry flood channels, coulees and cataracts eroded into Palouse loess and the typically flat-lying basalt flows that remain after cataclysmic floods within the southeastern part of Washington state. The Channeled Scablands were scoured by more than 40 cataclysmic floods during the Last Glacial Maximum and innumerable older cataclysmic floods over the last two million years. These floods were periodically unleashed whenever a large glacial lake broke through its ice dam and swept across eastern Washington and down the Columbia River Plateau during the Pleistocene epoch. The last of the cataclysmic floods occurred between 18,200 and 14,000 years ago.
Ridgefield National Wildlife Refuge is a National Wildlife Refuge and is overseen by the United States Fish and Wildlife Service. The refuge borders the Columbia River and is located west of the city of Ridgefield, Washington. The wildlife haven is split by Lake River. The refuge, which provides a year-round habitat and a migration stop for a variety of bird species, protects more than 5,200 acres (2,100 ha) of marshes, grasslands, and woodlands
Red Rock Lakes National Wildlife Refuge is a remote refuge located in the high elevation of the Centennial Valley, in the southwestern region of the U.S. state of Montana. Adjacent to Gallatin National Forest and near Yellowstone National Park, the refuge is an integral part of the Greater Yellowstone Ecosystem. Red Rock Lakes is best known for being the primary location for the efforts saving the trumpeter swan from extinction, which by 1932 had fewer than 200 known specimens in the United States and Canada. By the year 2002, an estimated 3,000 trumpeters were wintering on the refuge, many having migrated south from their summer range in Canada. The trumpeters are now so plentiful that efforts are being undertaken to help them reestablish historical migratory routes to areas further south in the Rocky Mountains and the Great Basin region. The elegant trumpeter swan is North America's largest waterfowl, with a wingspans of 8 feet and they can weigh up to 30 pounds (13 kg).
Baskett Slough National Wildlife Refuge is in northwestern Oregon, 10 miles (16 km) west of Salem in Polk County. The Refuge consists of 1,173 acres (4.75 km²) of cropland, which provide forage for wintering geese, 300 acres (1.2 km²) of forests, 550 acres (2.2 km²) of grasslands, and 500 acres (2.0 km²) of shallow water seasonal wetlands and 35 acres (0.14 km²) of permanent open water. In 1965, Baskett Slough National Wildlife Refuge was created to help ensure some of the original habitat remained for species preservation. The refuge is managed by the U.S. Fish and Wildlife Service, an agency of the U.S. Department of the Interior.
Drumheller Channels National Natural Landmark showcases the Drumheller Channels, which are the most significant example in the Columbia Plateau of basalt butte-and-basin Channeled Scablands. This National Natural Landmark is an extensively eroded landscape, located in south central Washington state characterized by hundreds of isolated, steep-sided hills (buttes) surrounded by a braided network of numerous channels, all but one of which are currently dry. It is a classic example of the tremendous erosive powers of extremely large floods such as those that reformed the Columbia Plateau volcanic terrain during the late Pleistocene glacial Missoula Floods.
Crab Creek is a stream in the U.S. state of Washington. Named for the presence of crayfish, it is one of the few perennial streams in the Columbia Basin of central Washington, flowing from the northeastern Columbia River Plateau, roughly 5 km (3.1 mi) east of Reardan, west-southwest to empty into the Columbia River near the small town of Beverly. Its course exhibits many examples of the erosive powers of extremely large glacial Missoula Floods of the late Pleistocene, which scoured the region. In addition, Crab Creek and its region have been transformed by the large-scale irrigation of the Bureau of Reclamation's Columbia Basin Project (CBP), which has raised water table levels, significantly extending the length of Crab Creek and created new lakes and streams.
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 Saddle Mountains consists of an upfolded anticline ridge of basalt in Grant County of central Washington state. The ridge, reaching to 2,700 feet, terminates in the east south of Othello, Washington near the foot of the Drumheller Channels. It continues to the west where it is broken at Sentinel Gap before ending in the foothills of the Cascade Mountains.
The Kofa National Wildlife Refuge is located in Arizona in the southwestern United States, northeast of Yuma and southeast of Quartzsite. The refuge, established in 1939 to protect desert bighorn sheep, encompasses over 665,400 acres (2,693 km2) of the Yuma Desert region of the Sonoran Desert. Broad, gently sloping foothills as well as the sharp, needlepoint peaks of the Kofa Mountains are found in the rugged refuge. The small, widely scattered waterholes attract a surprising number of water birds for a desert area. A wide variety of plant life is also found throughout the refuge. Kofa Wilderness takes up 547,719 acres of the refuge, making it the second largest wilderness area in Arizona.
The Turnbull National Wildlife Refuge is located six miles (10 km) south of Cheney, Washington, on the eastern edge of the Columbia Basin in Spokane County in northeastern Washington. Turnbull NWR encompasses more than 18,000 acres (7,300 ha) of the Channeled Scablands. The ecosystem that predominates the refuge is unique within the National Wildlife Refuge System and has characteristics that distinguish it from natural reserves worldwide. The combination of basalt outcrops, channeled canyons, and ponderosa pine forests infused in a diverse landscape of over 130 marshes, wetlands, and lakes creates an environment of aesthetic beauty as well as high quality wildlife habitat. The refuge is named for Cyrus Turnbull who lived on the site in the 1880s.
The U.S. state of Idaho borders six other U.S. states and one Canadian province. The states of Washington and Oregon are to the west, Nevada and Utah are to the south, and Montana and Wyoming are to the east. Idaho also shares a short border with the Canadian province of British Columbia to the north.
The Columbia Plateau State Park Trail is a 130-mile-long (210 km), 20-foot-wide (6.1 m) corridor in eastern Washington state maintained as part of the Washington State Park system. The rail trail runs along the abandoned right-of-way of the former Spokane, Portland and Seattle Railway.
The Columbia Plateau ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) encompassing approximately 32,100 square miles (83,139 km2) of land within the U.S. states of Washington, Oregon, and Idaho. The ecoregion extends across a wide swath of the Columbia River Basin from The Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Canada–U.S. border. It includes nearly 500 miles (800 km) of the Columbia River, as well as the lower reaches of major tributaries such as the Snake and Yakima rivers and the associated drainage basins. It is named for the Columbia Plateau, a flood basalt plateau formed by the Columbia River Basalt Group during the late Miocene and early Pliocene. The arid sagebrush steppe and grasslands of the region are flanked by moister, predominantly forested, mountainous ecoregions on all sides. The underlying basalt is up to 2 miles (3 km) thick and partially covered by thick loess deposits. Where precipitation amounts are sufficient, the deep loess soils have been extensively cultivated for wheat. Water from the Columbia River is subject to resource allocation debates involving fisheries, navigation, hydropower, recreation, and irrigation, and the Columbia Basin Project has dramatically converted much of the region to agricultural use.
The Ice Age Floods National Geologic Trail is a network of routes connecting natural sites and facilities that provide interpretation of the geological consequences of the Glacial Lake Missoula floods of the last glacial period that occurred about 18,000 to 15,000 years ago. It includes sites in Washington, Oregon, Idaho, and Montana. It was designated as the first National Geologic Trail in the United States in 2009.
Eastern Neck National Wildlife Refuge, a part of the Chesapeake Marshlands National Wildlife Refuge Complex, is a 2,286-acre (9.25 km2) island located at the confluence of the Chester River and the Chesapeake Bay. Established in 1962 as a sanctuary for migratory birds, Eastern Neck National Wildlife Refuge provides natural habitat for over 240 bird species — including bald eagles and transitory peregrine falcons — and is a major staging site for tundra swans.
Franz Lake National Wildlife Refuge is located in southwest Washington state, within the Columbia River Gorge National Scenic Area. The refuge provides a variety of habitats including riparian wetlands, Columbia River riparian corridor blocks, transitional woodlands from lower elevation willows, and cottonwoods to mid-elevation old-growth fir and cedar with associated native understory shrubs, open meadows, and numerous streams and seeps.
The Summer Lake Wildlife Area is a 29.6-square-mile (77 km2) wildlife refuge located on the northwestern edge of the Great Basin drainage in south-central Oregon. It is administered by the Oregon Department of Fish and Wildlife. The refuge is an important stop for waterfowl traveling along the Pacific Flyway during their spring and fall migrations. The Summer Lake Wildlife Area also provides habitat for shorebirds and other bird species as well as wide variety of mammals and several fish species. The Ana River supplies the water for the refuge wetlands.
