The San Gabriel Mountains rise sharply above the suburban sprawl of the Crescenta Valley, defining the northern boundary of this modern survey. Within the Angeles National Forest, the terrain is deeply incised by steep drainages like Millard Canyon and El Prieto Canyon, where the Dawn Mine remains a notable landmark of earlier extraction efforts. The transition from the rugged peaks to the developed valley floors illustrates the complex geography of the San Gabriel front, where residential neighborhoods in Altadena and La Cañada Flintridge push directly against the steep mountain slopes.
