Mount Bross

Mount Bross is a summit in the Mosquito Range of the Rocky Mountains, reaching about 4,321 meters (14,172 feet) in elevation. A mountain road and hiking paths ascend the peak, with evidence of past mining activity scattered throughout the slopes.

The peak was named after William Bross, a 19th-century property owner who operated mining in the nearby Alma area. The region became a significant mining center during the silver boom era of the American West.

Climbers visit this peak as part of pursuing high-altitude summits across Colorado. The mountain serves as a destination for those seeking personal achievement through mountaineering.

The best climbing season runs from June through September, with early morning starts recommended to avoid afternoon storms. Visitors should prepare for steep terrain and thin air at high elevation.

Since 2005 the summit has been private property, but an old mining road climbs to 13,356 feet (4,071 meters), making it one of America's highest drivable roads. This high point provides access for those who prefer not to hike to the official top.
