The environment and permafrost of the Mackenzie Delta area
The Mackenzie Delta, prograding northwestwards into the Beaufort Sea, is North America's largest arctic delta. This Holocene feature is bounded by rolling uplands to the east and the Richardson Mountains to the west. Treeline traverses the region, separating the subarctic boreal forest in south...

The Mackenzie Delta, prograding northwestwards into the Beaufort Sea, is North America's largest arctic delta.
