The northern foothills of the San Gabriel Mountains meet the expanding residential tracts of the San Gabriel Valley in this mid-1960s survey. The city of Glendora is the primary settlement, showing a dense grid of schools including Harding Academy and Goddard Jr High Sch, all serviced by the Atchison Topeka and Santa Fe railroad. To the north, the landscape shifts abruptly into the Angeles National Forest, where steep canyons are managed for water and research. The massive San Gabriel Reservoir and Morris Reservoir dominate the upper reaches, with the latter notably featuring the US Naval Ordnance Testing Station. This area also includes the specialized terrain of the San Dimas Experimental Forest, containing landmarks like the Johnstone Peak lookout tower. Recreational sites and remote outposts like Follows Camp and Camp Oak Grove reflect the region's importance for both watershed protection and mountain access.
