at Anaktuvuk Pass Ranger Station is 2b with an average annual extreme minimum temperature of . Perennial snowfields and glaciers, which are crucial to various ecosystems within the park, are decreasing at a rapid rate due to warming temperatures. From 1985 to 2017, the area of these snowfields decreased in size by 13 km2. These warming temperatures have also resulted in the thawing of permafrost which has directly affected the stability of the soil. As permafrost thaws, it exposes the bare soil to the elements which leads to erosion and slope failures.

History

Nomadic peoples have inhabited the Brooks Range for as many as 12,500 years, living mainly on caribou and other wildlife. The Mesa site at Iteriak Creek has yielded evidence of occupation between 11,500 and 10,300 years before the present. Later sites from around 6,000 years before present have yielded projectile points, stone knives and net sinkers. The

(ASTt) of about 4,500 BP has also been documented. A late phase of the ASTt from between 2500 and 950 BP, the Ipuitak phase, has been documented in the park at the Bateman Site at Itkillik Lake. The earliest Inupiat people appeared about 1200 AD at the coast and spread to the Brooks Range, becoming the

. The Nunamiut people, who had left much of their traditional homelands following a crash in the caribou populations in the early 1900s, resumed a relatively isolated subsistence way of life after returning to the mountains in the late 1930s.

The Alaskan interior was not explored until the late 19th century, shortly before discovery of gold in the Klondike brought prospectors to Alaska. Some encampments of explorers and survey parties have been identified in the park. A few small mining operations were established in the early 20th century, never amounting to much. The park's name dates to 1929, when wilderness activist Bob Marshall, exploring the North Fork of the
