Summit Mountain is an 8,775-foot peak on Glacier National Park's Continental Divide. Formed by the Lewis Overthrust with Belt Supergroup rocks pushed over younger strata, it was sculpted by Pleistocene glaciers. The main ascent follows the Autumn Creek Trail from Marias Pass for about 5 miles round-trip, starting near the saddle with Little Dog Mountain and gaining roughly 1,820 ft. The prime window is late June through mid-September; prepare for exposed sections and rapidly changing weather.
