Blue Mountain is a 6,004-foot-elevation (1,830 meter) mountain summit located within Olympic National Park in Clallam County of Washington state. Blue Mountain is situated in the Daniel J. Evans Wilderness, 13 miles southeast of Port Angeles and 11 miles southwest of Sequim. Topographic relief is significant as the south aspect rises 4,000 feet (1,220 meters) above Gray Wolf River in approximately 2.5 miles. The mountain's name is due to a soft, blue haze that forms around the mountain in the summer. New settlers to the Olympic Peninsula near the end of the 19th century brought devastating fires started by land clearing and logging activities. The Dungeness Fire of 1891 burned about 30,000 acres, destroying much of the forest around Blue Mountain.
