The San Gorgonio Pass serves as the central corridor for this 2015 study, dominated by the developed centers of Banning and Cabazon. This region marks a significant transition point where the San Jacinto Mountains rise to the south, countered by the steep terrain of the San Bernardino National Forest to the north. A critical piece of infrastructure, the Colorado River Aqueduct, snakes across the southern foothills, illustrating the engineering required to move water through this arid landscape.
