Resolution Mountain Road is the last leg of the Dirty Copper Triangle. The road is an extremely popular 4-wheel drive road, heavily promoted by commercial rental operations. Couple this with a brutal 5.5 mile climb averaging over 10% grade for the top 2.5 miles, and the final 1.5 miles at nearly 14% can make this climb frustrating.
There are three distinct road intersections along this climb: the first near the bottom with 708, McAllister Gulch Road on the left; the second 715, Pearl Creek Road on the right at 1.5 miles; and the last 751, Ptarmigan Road above timberline on the left 1/2 mile from the summit of Ptarmigan Pass. Top out at Ptarmigan Pass, and exalt in the fact that you've made it to the top!
