Mackenzie Reaches the Mackenzie River Delta

Mackenzie set out by canoe on 3 July 1789, hoping the Dehcho would lead to Cook Inlet in Alaska.

On behalf of the North West Company, Mackenzie travelled to Lake Athabasca, where in 1788 he had helped found Fort Chipewyan. From there he set out by canoe on the river the local Dene First Nations people called the Dehcho, departing on 3 July 1789. He believed the river would lead to Cook Inlet in Alaska; it was later named the Mackenzie River in his honour.
