Cuyamaca Mountains
The Cuyamaca Mountains, locally the Cuyamacas, are a mountain range of the Peninsular Ranges in San Diego County, California. The mountain range runs roughly northwest to southeast. The Laguna Mountains are directly adjacent to the east, with Palomar Mountain and Hot Springs Mountain more distant to the north.
Most of the range consists of extensive oak forest and chaparral, part of the California montane chaparral and woodlands ecoregion, interspersed with pine forests and lush riparian zones, featuring year round creeks and waterfalls. The San Diego River and Sweetwater River both have their headwaters in these mountains, which flow over 50 miles to the ocean. The pine forests were extensively burned by the 2003 Cedar Fire, along with many large areas of chaparral and oak woodland, which has since experienced slow and steady regrowth.
The high elevation produces a risk of snowfall throughout the winter months. Cuyamaca Peak, at, is San Diego County's second highest, after Hot Springs Mountain.
Geography
The range's highest peaks are Cuyamaca Peak at, North Peak at, Middle Peak at, and Stonewall Peak at. The San Diego River and the Sweetwater River both have headwaters in the Cuyamacas. The Cuyamaca Reservoir lies adjacent to the east side of the range.Mountains are primarily protected within the Cleveland National Forest. Cuyamaca Rancho State Park, with California oak woodlands habitat, is located in the range.
The former mining town of Julian is in the northern section, and the towns of Descanso, Pine Valley and Guatay is in the southern. Alpine, a more populated town with some dense residential development, lies directly to the west of the range, bordering the Lakeside and El Cajon areas.
Interstate 8 passes through the southern part of the Cuyamaca Mountains. California State Route 79, known as the Cuyamaca Highway, runs north–south along the eastern part of the mountains.
