Book excerpt: In its heyday, Colorado had more than 175 ski areas operating on the slopes of the Rocky Mountains, and while many of those resorts have shut down, their runs still shelter secret stashes of snow. Pristine slopes await backcountry powder hounds out to discover these chutes and steeps, bunny hills and bumps. Chronicling the history of more than 36 of these "lost resorts," Powder Ghost Towns provides the beta for how to ski and board these classic runs today, with comprehensive information on trailheads, where to skin up, and the best descents. Coverage ranges from southern Wyoming's Medicine Bow Mountains to the Colorado-New Mexico border, including famous old resorts like Hidden Valley in Rocky Mountain National Park.
