Mount Bross is a high mountain summit in the Mosquito Range of the Rocky Mountains of North America. The fourteener is located in Pike National Forest, northwest by north (bearing 327ð) of the Town of Alma in Park County, Colorado, United States. Mount Bross is named in honor of William Bross, who owned property in the area.
It is often climbed together with Mount Lincoln and nearby Mount Democrat.
In 2005, the summit of Mount Bross was closed to the public because of safety concerns related to mines and trail access through private land.
