Clark Mountain is located in the Glacier Peak wilderness of north-central WA. It is a great non-technical climb with excellent views of the Dakobed Range, Glacier Peak, and the Napeequa Valley. The climb starts at 2,300 ft in the White River Valley (not to be confused with the White River near Mt. Rainier) and tops out at 8,502 ft. The shortest route to climb the mountain is right up from the White River Valley (~16 miles RT), but the fastest route is probably the Boulder Creek route (~23 miles RT) which utilizes trails leading all the way up to 6,000 feet. The trails also allow for more running (except in the sections where they are not brushy and overgrown). I chose the Boulder Creek route and was able to reach the summit 3:34 after beginning. After 16 minutes on top, I made the return trip in 2:54 (6:44 roundtrip). The climb entailed about 23 miles and 7,000 feet of elevation gain. See many more photos on the complete trip report!
