Badlands National Park is a national park of the United States in southwestern South Dakota. The park protects 242,756 acres of sharply eroded buttes and pinnacles, along with the largest undisturbed mixed grass prairie in the United States. The National Park Service manages the park, with the South Unit being co-managed with the Oglala Lakota tribe.
Devils Lake is a lake in the U.S. state of North Dakota. It is the largest natural body of water and the second-largest body of water in North Dakota after Lake Sakakawea. It can reach a level of 1,458 ft (444 m) before naturally flowing into the Sheyenne River via the Tolna Coulee. On June 27, 2011, it reached an unofficial historical high elevation of 1,454.3 ft (443.3 m). The cities of Devils Lake and Minnewaukan take their name from the lake as does the Spirit Lake Reservation, which is located on the lake's southern shores.
The Missouri Coteau, or Missouri Plateau, is a large plateau that stretches along the eastern side of the valley of the Missouri River in central North Dakota and north-central South Dakota in the United States. In the Canadian provinces of Saskatchewan and Alberta this physiographic region is classified as the Uplands Missouri Coteau, which is a part of the Great Plains Province or Alberta Plateau Region, which extends across the southwest corner of the province of Saskatchewan as well as the southeast corner of the province of Alberta. Historically, in Canada the area was known as the Palliser's Triangle and regarded as an extension of the Great American Desert and unsuitable for agriculture and thus designated by Canadian geographer and explorer John Palliser. The terrain of the Missouri Coteau features low hummocky, undulating, rolling hills, potholes, and grasslands. Apart from being a geographical area, the Missouri Coteau also has a cultural connection to the people of the area, the Métis people of South Dakota, along with other Indigenous groups. The history of this plateau is large, and the Missouri Coteau has a significance to these people.
The Pembina River is a tributary of the Red River of the North, approximately 319 miles (513 km) long, in southern Manitoba in Canada and northeastern North Dakota in the United States. It drains an area of the prairie country along the Canada–US border, threading the Manitoba-North Dakota border eastward to the Red River. Via the Red River, Lake Winnipeg and the Nelson River, it is part of the watershed of Hudson Bay.
The National Natural Landmarks (NNL) Program recognizes and encourages the conservation of outstanding examples of the natural history of the United States. It is the only national natural areas program that identifies and recognizes the best examples of biological and geological features in both public and private ownership. The program was established on May 18, 1962, by United States Secretary of the Interior Stewart Udall.
Buffalo River State Park is a state park of Minnesota, United States, conserving a prairie bisected by the wooded banks of the Buffalo River. Together with the adjacent Bluestem Prairie Scientific and Natural Area co-owned by The Nature Conservancy and Minnesota's Department of Natural Resources, it protects one of the largest and highest-quality prairie remnants in Minnesota. It used to offer a man-made swimming pond close to the Fargo–Moorhead metropolitan area, however, that has not been open since 2018. Presently, it is most popular for its high quality educational programming, swimming in the Buffalo River, and picnicking. The 1,068-acre (432 ha) park is located just off U.S. Route 10 in Clay County, 4.5 miles (7.2 km) east of Glyndon and 14 miles (23 km) east of Moorhead.
The Chase Lake Prairie Project is considered the "National Flagship Project" of the North American Waterfowl Management Plan (NAWMP). The goal is to rehabilitate 5,500,000 acres (2,200,000 ha) of wetland around Chase Lake on the Missouri Coteau. The project was dedicated in September 1989.
The Prairie Pothole Region (PPR) is an expansive area of the northern Great Plains that contains thousands of shallow wetlands known as potholes. These potholes are the result of glacier activity in the Wisconsin glaciation, which ended about 10,000 years ago. The decaying ice sheet left behind depressions formed by the uneven deposition of till as buried ice blocks melted in ground moraines. These depressions are called potholes, glacial potholes, kettles, or kettle lakes. They fill with water in the spring, creating wetlands, which range in duration from temporary to semi-permanent. The region covers an area of about 800,000 sq. km and expands across three Canadian provinces and five U.S. states. The hydrology of the wetlands is variable, which results in long term productivity and biodiversity. The PPR is a prime spot during breeding and nesting season for millions of migrating waterfowl.
The Antler River is located in the Prairie Pothole Region of North America's Great Plains in south-eastern Saskatchewan and south-western Manitoba in Canada in an area known as Palliser's Triangle. Its source is in Saskatchewan's Moose Mountain Upland and it is a major tributary of the Souris River. As a result, its flood levels are monitored by the United States Geological Survey.
The Traverse Gap is an ancient river channel occupied by Lake Traverse, Big Stone Lake, and the valley connecting them at Browns Valley, Minnesota. It is on the border of the U.S. states of Minnesota and South Dakota. Traverse Gap has an unusual distinction for a valley: it is transected by a continental divide, and in some floods, water has flowed across that divide from one drainage basin to the other. Before the Anglo-American Convention of 1818, it marked the border between British territory in the north and U.S.—or, earlier, French—territory in the south.
Pickerel Lake is a 955-acre spring-fed lake located in Day County, South Dakota, United States. Pickerel Lake is part of the Glacial Lakes Region that encompasses much of Northeast South Dakota and stretches along the Coteau des Prairies hills. The area was formed thousands of years ago by glacial activity. Many of the depressions left behind were filled by melting glaciers. This area is also referred to as the Prairie Pothole Region. Pickerel Lake is one of the deepest natural lakes in South Dakota. The name originated from an American Indian name meaning "where you spear long fish." Excursion boats were common until the early 1900s. A fish hatchery was built in 1929 and abandoned in 1979, when a new facility was built at Blue Dog Lake.
South Dakota is a state located in the north-central United States. It is usually considered to be in the Midwestern region of the country. The state can generally be divided into three geographic regions: eastern South Dakota, western South Dakota, and the Black Hills. Eastern South Dakota is lower in elevation and higher in precipitation than the western part of the state, and the Black Hills are a low, isolated mountain group in the southwestern corner of the state. Smaller sub-regions in the state include the Coteau des Prairies, Missouri Coteau, James River Valley, and the Dissected Till Plains. Geologic formations in South Dakota range in age from two billion-year-old Precambrian granite in the Black Hills to glacial till deposited over the last few million years. South Dakota is the 17th-largest state in the country.
Straddling the headwaters of the Minnesota River in west-central Minnesota, Big Stone National Wildlife Refuge is within the heart of the tallgrass prairie's historic range. Today, less than one-percent of tallgrass prairie remains.
Tewaukon National Wildlife Refuge is located in southeastern North Dakota along the western edge of the northern tallgrass prairie, about 5 miles (8.0 km) south of Cayuga, in Sargent County. The Wild Rice River flows through the Refuge and then into Lake Tewaukon. Established in 1945, the 8,363-acre (33.84 km2) Refuge is located in the Prairie Pothole Region, one of the most biologically productive areas on earth. It lies within the Tewaukon Wetland Management District.
Last Mountain Lake Bird Sanctuary is a National Historic Site of Canada, located in the rural municipality of Last Mountain Valley No. 250 in Saskatchewan. The migratory bird sanctuary was the first established in North America. The 47.36 km2 (18.29 sq mi) area is within the Last Mountain Lake National Wildlife Area, an International Biological Program site, and includes adjacent uplands.
Sibley Lake is a body of water located six miles north of Dawson in Kidder County, North Dakota. The lake has a surface area listed at 1,304 acres (528 ha). It is fished for walleye and perch. In 1975, Sibley Lake was designated as a National Natural Landmark by the National Park Service.
Moose Mountain Upland, Moose Mountain Uplands, or commonly Moose Mountain, is a hilly plateau located in the south-east corner of the Canadian province of Saskatchewan, that covers an area of about 13,000 square kilometres (5,000 sq mi). The upland rises about 200 metres (660 ft) above the broad, flat prairie which is about 600 metres (2,000 ft) above sea level. The highest peak is "Moose Mountain" at 830 metres (2,720 ft) above sea level. The upland was named Moose Mountain because of the large number of moose that lived in the area. When it was originally used by fur traders, Métis, and the Indigenous peoples, the plateau was called Montagne a la Bosse, which is French for "The Mountain of the Bump or Knob".
Long Creek is a river in central North America that begins in Saskatchewan, flows south-east into North Dakota, and then flows back north into Saskatchewan. It is a tributary of the Souris River. The Souris River drains into the Assiniboine River, which is part of the Red River drainage basin in a region called the Prairie Pothole Region of North America, which extends throughout three Canadian provinces and five U.S. states. It is also within Palliser's Triangle and the Great Plains ecoregion. In 1957, a dam was built on Long Creek near where it meets the Souris River to create Boundary Dam Reservoir.
Buffalo Slough is a glacial prairie pothole wetland, and adjacent patch of bluestem tallgrass prairie, in Lake County, South Dakota, United States. The complex is located near Chester in far eastern South Dakota. Owned by the State of South Dakota, the formation was listed as a National Natural Landmark in 1980.
Cottonwood Slough-Dry Run is a glacial wetland adjacent to Lake Kampeska in Roberts County, South Dakota, United States. The complex is located near Watertown in eastern South Dakota. Owned by the State of South Dakota and the private sector, the wetland was listed as a National Natural Landmark in 1975.
