Great Slave Lake in the context of "Dogrib language"

Mount Mazama (Klamath: Tum-sum-ne) is a complex volcano in the western U.S. state of Oregon, in a segment of the Cascade Volcanic Arc and Cascade Range. The volcano is in Klamath County, in the southern Cascades, 60 miles (97 km) north of the Oregon–California border. Its collapse, due to the eruption of magma emptying the underlying magma chamber, formed a caldera that holds Crater Lake (Giiwas in the Native American language Klamath). Mount Mazama originally had an elevation of approximately 12,000 feet (3,700 m), but following its climactic eruption this was reduced to 8,157 feet (2,486 m). Crater Lake is 1,943 feet (592 m) deep, the deepest freshwater body in the U.S. and the second deepest in North America after Great Slave Lake in Canada.

Mount Mazama formed as a group of overlapping volcanic edifices such as shield volcanoes and small composite cones, becoming active intermittently until its climactic eruption 7,700 years ago. This eruption, the largest known within the Cascade Volcanic Arc in a million years, destroyed Mazama's summit, reducing its approximate 12,000-foot (3,700 m) height by about 1 mile (1,600 m). Much of the edifice fell into the volcano's partially emptied neck and magma chamber, creating a caldera. The region's volcanic activity results from the subduction of the offshore oceanic plate, and is influenced by local extensional faulting. Mazama is dormant, but the U.S. Geological Survey says eruptions on a smaller scale are likely, which would pose a threat to its surroundings.

Yellowknife is the capital, largest community, and the only city in the Northwest Territories, Canada. It is on the northern shore of Great Slave Lake, about 400 km (250 mi) south of the Arctic Circle, on the west side of Yellowknife Bay near the outlet of the Yellowknife River.

Yellowknife and its surrounding water bodies were named after a local Dene tribe, who were known as the "Copper Indians" or "Yellowknife Indians", today incorporated as the Yellowknives Dene First Nation. They traded tools made from copper deposits near the Arctic Coast. Modern Yellowknives members can be found in the city as well as in the adjoining, primarily Indigenous communities of Ndilǫ and Dettah.

The Mackenzie River (French: Fleuve (de) Mackenzie; Slavey: Deh-Cho [tèh tʃʰò], literally big river; Inuvialuktun: Kuukpak [kuːkpɑk], literally great river) is a river in the Canadian boreal forest and tundra. It forms, along with the Slave, Peace, and Finlay, the longest river system in Canada, the second largest drainage basin of any North American river after the Mississippi.

The Mackenzie River flows through a vast, thinly populated region of forest and tundra entirely within the Northwest Territories in Canada, although its many tributaries reach into five other Canadian provinces and territories. The river's main stem is 1,738 kilometres (1,080 mi) long, flowing north-northwest from Great Slave Lake into the Arctic Ocean, where it forms a large delta at its mouth. Its extensive watershed drains about 20 percent of Canada. It is the largest river flowing into the Arctic from North America, and including its tributaries has a total length of 4,241 kilometres (2,635 mi), registering the 13th longest river system and 12th largest drainage basin on Earth.

Hay River (South Slavey: Xátł’odehchee [xátɬ’otɛhtʃʰe]), known as "the Hub of the North", is a town in the Northwest Territories, Canada. The town is located on the south shore of Great Slave Lake at the mouth of the Hay River. It is separated into two sections: A new town and an old town. The Hay River/Merlyn Carter Airport is located between the two sections. The town is situated in the South Slave Region, and along with Fort Smith, the town is home to one of the two regional offices in the region.
