Located within Gates of the Arctic National Park, the Arrigetch Peaks have long been a landmark to the Nunamiut people of northwest Alaska. Carved by glacial ice and running water, the conspicuous granite pinnacles rise thousands of feet above the surrounding glacial valleys of tundra and boreal forest. The Arrigetch Peaks illustrate several phases of alpine glacier activities and reveal abrupt transitions from metamorphic to granitic rock. This National Natural Landmark was designated in 1968, and is comprised of 38,313 acres.
