Of the 20 million Colorado summer visitors, hundreds of thousands scramble throughout the Colorado Rockies * Route descriptions include length, difficulty and main features * Includes GPS waypoints for critical points (crux moves) and color topos for each route "Colorado Scrambles" includes more than 50 scrambling routes in the major mountain ranges of Colorado. Author Dave Cooper ("Colorado Snow Climbs") climbed each of these high-quality routes, selecting them based on challenge, rock quality, location and interesting route finding. In scrambling, climbers use both hands and feet to get up a mountain, using a rope, if at all, only to protect short sections. Other than a rope and a little hardware, all a climber needs is a good pair of boots, a daypack, and foul-weather gear. In technical terms, scrambling is moving over 3rd- and 4th-class rock, often with a considerable amount of exposure.
