Colonel Bob Mountain is a summit on Washington’s Olympic Peninsula in Grays Harbor County, where it ranks among the county’s highest points, surpassed only by Gibson Peak. An 1890 map by Henry Fisher called it McCallas Peak. The first recorded ascent occurred in 1893, when Clark Pealer, J. N., and Robert Locke climbed the mountain and named it for the orator Robert G. Ingersoll. Their party left a cairn and a written record on the summit, and that record was rediscovered in 1930. The mountain’s name now also identifies the surrounding wilderness area.
