2013 Map of Shadow Mountain

About this map

Grand Lake and the interconnected waters of Shadow Mountain Lake and Lake Granby anchor this high-altitude landscape where the headwaters of the Colorado River meet complex water-management infrastructure. The 2013 survey documents the engineering of the Alva B Adams Tunnel and the Granby Pump Canal, which facilitate the trans-continental diversion of water through the West Portal. This alpine region is defined by its recreational and conservation footprint within Arapaho National Forest and Rocky Mountain National Park, featuring a dense network of trails and campsites. Long-distance hikers are served by the Continental Divide National Scenic Trail, while boaters and campers utilize facilities like the Hilltop Boat Ramp, Green Ridge Campground, and Pine Beach Area. Named peaks like Shadow Mountain and Mount Acoma rise above the series of bays and islands, including Elephant Island and Harvey Island, that characterize these mountain reservoirs.
