An ascent of Mount Stimson by Bob Bolton, Duane Gilliland, Greg Slayden, Edward Earl, and Adam Helman in August 2008 is documented below by links to Greg Slayden's photo album and original report.

The route was a novel, eastern approach beginning at Two Medicine Lake; ultimately climbing the southeast ridge after gaining the Mount Stimson / Mount Pinchot saddle.

The expedition consumed five days due to the large distances (over 40 miles), total elevation gain (about 13,000 feet), and slow bushwhacking.

An ascent of Mount Stimson by Jim Perkins and two companions in August 2008 is documented below by seven photographs and captions courtesy of Jim.

Their route was the "standard" Coal Creek Route from the west, and consumed only two days.
