Mount Bross, a 14,178-foot peak in Colorado’s Mosquito Range of the Rocky Mountains, rises in Pike National Forest near Alma and ranks among the state’s fourteeners as its twenty-second highest mountain. Named for local property owner William Bross, it is commonly climbed with nearby Mount Lincoln and Mount Democrat as part of a well-known high alpine group. Its summit closed to the public in 2005 because of safety hazards from old mines and trail access across private land. That closure highlights the mountain’s significance not just as a popular summit, but as a place where Colorado’s mining past and outdoor recreation intersect.
