UP 4014 over Cajon Pass & Beaumont Hill

Cajon Pass is a mountain pass (elevation of 3,777 feet) between the San Bernardino Mountains to the east and the San Gabriel Mountains to the west in Southern California. Technically, the Cajon Pass starts at Devore and runs for approximately 20 miles to Victor Valley. All railroad tracks traversing the canyon are owned by BNSF Railway and Union Pacific Railroad.. The word Cajon is Spanish for “Box” or “drawer” (cajón). The Native American people who lived in the area had used the pass for thousands of years. In 1772, Pedro Farges, a Spanish officer, marched from San Diego to Monterey and became the first European to cross Cajon Pass. Wikipedia
