About the Brooks Range Tundra

The Brooks Range is a series of rugged mountains running West to East from northern Alaska into the Yukon Territory in Canada, and the Brooks Range Tundra is the region that encompasses much of this range. The mountains are formed from uplifted sedimentary rock, and deeply cut by glaciation. Peak elevation ranges from 2600 feet in the west to 8000 feet in the central to eastern side of this region. Some small glaciers persist in this area at higher elevations.

Vegetation cover is sparse, and mostly consists of dwarf scrubland, with some graminoid (grasslike) vegetation in valleys and lowlands, and barren talus slopes.

This region gradually changes to the Alaska Tundra in the north, and to the south, variously to the Alaska Boreal Interior and Boreal Cordillera, with the easternmost part also bordering the Taiga Cordillera.

The only permanent settlements are a small portion of Native Americans on the US side of this region, who practice subsistence hunting, fishing, and gathering. There is some seasonal wildlife trapping, hunting, and tourism, mainly in the Canadian national parks located here. There is also mining in the region.
