Colorado (USA) — Biggest Lines

⎜COLORADO ROCKIES

The Colorado Rockies are America’s winter playground. There are more ski resorts within the boundaries of this state than any other. The snow quality is high, access is exceptional, and the enthusiasm of its residents for winter sports is unparalleled in the United States. Boulder, Colorado, situated in the foothills of the Front Range, is the headquarters for the American Mountain Guides Association, the principal licensing organization for mountain guiding in the U.S. There are perhaps more licensed guides living and working here than anywhere else in the world outside of Chamonix, France. The Front Range is where most of the conventional action occurs, but the San Juans in the southwest corner of the state offer the highest concentration of ‘14ers’ (peaks higher than 14,000 feet), some of Colorado’s most beautiful scenery, and the vast majority of its steepest lines. Though snowfall is less copious than in other parts of the state, the mountains in and around the beautiful mountain town of Telluride offer some of the biggest and most aesthetic lines in the ski world. Silverton, just over the pass in Red Mountain country, adjacent to the old mining town of the same name, is nearly as dramatic, gets more snow, and is the only resort in the U.S. that requires the services of a professional guide to access its terrain. Avalanches are a major hazard in this continental snowpack, especially in the early and middle part of winter. Be extremely careful!

*The San Juan Mountains are the deeply shaded (i.e.: steep!) mountain range in the southeast corner of the map. This is where the highest concentration of tall peaks are in the state, and where the historic mountain towns of Durango, Telluride, Ridgway, Ouray, and Silverton sit. The Front Range just west of the city of Denver is the north-south line of mountains in the center of the map. The Elk Mountains are the high peaks just north and west of center, and include the famed mountain towns of Aspen, Vail, and Crested Butte. Click on image for Google Map.
