Mount Dickerman, Mountain summit in Snohomish County, Washington, United States

Mount Dickerman is a mountain in Mount Baker-Snoqualmie National Forest, northwest of Barlow Pass along the Mountain Loop Highway. A strenuous four-mile trail climbs from the highway to the summit, where views take in Glacier Peak, Monte Cristo Peak and Sloan Peak. Its slopes lie in the marine west coast climate zone of western North America, with wet, heavy snow and high avalanche danger in winter.

The mountain was named in the early 1900s after Alton L. Dickerman, a consulting geologist who worked for a mining company operating in the area. This naming reflects a period when the region was actively being explored for natural resources and mining opportunities.

The name honours Alton Leslie Dickerman Sr. (1850–1921), consulting geologist for the Monte Cristo Mining Company, whose work tied the peak to the Monte Cristo mining district. Hikers on the four-mile trail pass through terrain once prospected for the same company's mineral claims.

The trail is demanding and requires sturdy hiking boots and plenty of water, especially on warm days. Start your hike early in the day to have plenty of daylight, and be prepared for changing weather since clouds can move in quickly at higher elevations.
