Alexander Mackenzie reaches the Mackenzie River delta10.7.1789

The Mackenzie River is the largest and longest river system in Canada. It flows through a vast, isolated region of forest and tundra entirely within the country's Northwest Territories, although its many tributaries reach into four other Canadian provinces and territories. The river's mainstem runs 1,738 kilometres (1,080 mi) in a northerly direction to the Arctic Ocean, draining a vast area nearly the size of Indonesia. It is the largest river flowing into the Arctic from North America, and with its tributaries is one of the longest rivers in the world.


The Mackenzie (previously Disappointment) River was named after Alexander Mackenzie, who travelled the river in the hope it would lead to the Pacific Ocean, but instead reached its mouth on the Arctic Ocean on 14 July 1789. No European reached its mouth again until James Franklin on 16 August 1825. The following year he traced the coast west until blocked by ice while John Richardson (naturalist) followed the coast east to the Coppermine River. In 1849 William Pullen reached the Mackenzie from Bering Strait.

The Royal Canadian Mint honoured the 200th anniversary of the naming of the Mackenzie River with the issue of a silver commemorative dollar in 1989.

In 2008, Canadian and Japanese researchers extracted a constant stream of natural gas from a test project at the Mallik methane hydrate field in the Mackenzie Delta. This was the second such drilling at Mallik: the first took place in 2002 and used heat to release methane. In the 2008 experiment, researchers were able to extract gas by lowering the pressure, without heating, requiring significantly less energy. The Mallik gas hydrate field was first discovered by Imperial Oil in 1971–1972.
