The Arrigetch Peaks are a cluster of rugged granite spires in the Endicott Mountains of the central Brooks Range in northern Alaska. The name Arrigetch means 'fingers of the outstretched hand' in the Inupiat language. The peaks ring the glacial cirques at the head of the Kobuk River and 2 tributaries of the Alatna River: Arrigetch Creek and Aiyagomahala Creek (Creek 4662). They are located at latitude 67 degrees 24' N and longitude 154 degrees 10' W. All of the summits of the peaks are around 6,000 ft, 1825 m elevation. The Arrigetch Peaks area was designated as a National Natural Landmark in 1968 for its spectacular geography.
The earliest recorded visit was in 1911 by Philip Smith, a geologist. The renowned conservationist Robert Marshall traveled through the area in the 1930s. These trips were described in his 1933 book Arctic Wilderness, and posthumous Alaska Wilderness: Exploring the Central Brooks Range. A British climbing party completed the first successful rock climbing expedition to the peaks in 1964. The peaks have been visited by a number of rock climbing expeditions since then.
