Description

Pyramid Peak is part of the Aleutian Range.^[5] This iconic landmark of the Dutch Harbor area is set two miles (3.2 km) south of Unalaska on Unalaska Island of the Aleutian Islands. Precipitation runoff from the mountain drains into Captains Bay and Iliuliuk Bay. Topographic relief is significant as the summit rises over 2,100 feet (640 meters) above tidewater of Captains Bay in approximately one mile (1.6 km). The mountain's descriptive toponym was published in 1875 by the United States Coast Survey and has been officially adopted by the United States Board on Geographic Names.^[4]
