A trail my wife and have snowshoed countless times is Mayflower Gulch Trail. It's about 6 miles off of I70 from the Copper Mountain exit going towards Leadville. The parking area is on the left hand side, 2nd parking area North of Clinton Reservoir. If you see the reservoir you've gone to far. A couple old mining cabins at the end of the trail. When you get to the cabins and a gate, the trail swichbacks up a ridge to the North to the base of Fletcher mountain, great views, it overlooks Clinton Reservoir. About 5 EZ miles round trip.
