The Cuyamaca Mountains, locally the Cuyamacas, are a mountain range in San Diego County, California. The mountains run roughly northwest to southeast. The highest elevations are Cuyamaca Peak at 6,512 feet (1,985 m) and Stonewall Peak at 5,700 feet (1,700 m). The San Diego River and the Sweetwater River both rise in the Cuyamacas. The Cuyamaca Reservoir lies adjacent to the east side of the range.
Gold was discovered in the Cuyamacas in 1870 and the mountains were subject to a gold rush. Towns and encampments of Coleman City, Branson City, Eastwood, Julian, and Banner sprang up to support the miners. First a mining camp called Stonewall(1873-1876), then the company town of Stratton (1887-1888), renamed Cuyamaca City (1888-1906), at its peak had a population of 500 and served the Stonewall Mine. The town was abandoned after mining operations ceased, and few traces of it exist. The site of the town now lies within Cuyamaca Rancho State Park. Other gold mines were supported by the town of Julian, which celebrates its mining history with an annual festival called Gold Rush Days. The Eagle-High Peak Mine, no longer productive, is now a museum and gives daily tours.
