The route we suggest for Mt. Silverheels is also outlined in "The Guide to the Colorado Mountains." This is what we used when we climbed this summit in 1989. The main difference will be the coordinates we'll provide to help hikers avoid a couple of difficulties. Roach's Book, "Colorado's Thirteeners" covers this route and G&M also have a variation.
Mt. Silverheels by this route is a Class 2 hike that utilizes an old road and crosses mostly tundra terrain with a limited amount of willows to deal with. The trailhead is accessible to any passenger car. This route is probably the shortest mileage hike to the summit available for passenger car owners. This hike is a fairly good family hike.
