The Laguna Mountains are a section of the Peninsular Ranges in eastern San Diego County, California. The mountains run in a NW-SE alignment for approximately 20 miles.
The Laguna Mountains are bordered by the Cuyamaca area on the W and the Colorado Desert on the E, where the mountains form a steep escarpment along the Laguna Salada Fault. To the N, the Laguna Mountains are bounded by the Elsinore Fault, and to the south, by Cameron Valley and Thing Valley. The highest point is Cuyapaipe Mountain at 6,378 feet. The mountains are largely contained within the Cleveland National Forest.The Laguna Mountains extend northwest about 35 mi from the Mexican border at the Sierra Juárez range (Wikipedia).
