map of Muskoxen distribution in nwt

Distribution

Muskoxen crossed into Northern America about 90,000 years ago when the Bering Strait was dry land. When the last glacier covered North America, muskoxen survived in ice-free areas or ‘glacial refugia’ in the northern Arctic islands and Greenland. As the ice retreated, muskox spread throughout northern Canada and Greenland before moving westward into Alaska.

Today, muskoxen in the Northwest Territories (NWT) are found on Banks, Eglinton, Melville and Victoria Islands and on the mainland from the Arctic coast southwest to Artillery Lake.
