The Coppermine River is a river located in the Canadian provinces of the Northwest Territories and Nunavut .

Surname

The river got its name from the copper deposits on its lower reaches.

geography

The source of the Coppermine River is at Lac de Gras . From there it flows in a generally northerly direction to the Coronation Gulf , a bay in the Arctic Ocean. The village of Kugluktuk (formerly called Coppermine) is located near the river mouth.

history

Samuel Hearne explored the Coppermine River in 1771, traveled to its mouth and was the first European to reach the Arctic Ocean by land. The Bloody Falls massacre, described by Hearne, took place at the Bloody Falls . In the Coppermine Expedition from 1819-1822 Sir John Franklin explored the mouth of the Coppermine River.

geology

Lava eruptions near the Coppermine River created an extensive volcanic plateau about 1,200 million years ago with an area of ​​about 170,000 km² and a lava volume of at least 500,000 km³. This lava was formed simultaneously with the great Muskox intrusion and the extensive Mackenzie Dike Swarm to the southeast. It is believed to originate from a mantle plume center , the Mackenzie Hotspot .
