Indian Mountain is a remote 7,133-foot (2,174-metre) mountain summit in the Skagit Range of the North Cascades, in Whatcom County of Washington state. Indian Mountain is situated in North Cascades National Park, 7 miles south of the Canada–United States border. Its nearest higher neighbor is Red Face Mountain, 1.14 mi (1.83 km) to the southeast, and Whatcom Peak rises 2.9 mi (4.7 km) to the south. Although modest in elevation, relief is significant since this peak rises over 4,100 feet above Brush Creek Valley in approximately one mile. Precipitation runoff from Indian Mountain drains into tributaries of the Chilliwack River.
