The San Gabriel Mountains dominate this 1933 advance sheet, revealing the early infrastructure of the Angeles National Forest before widespread suburban expansion reached this high into the canyons. Small settlements and specialized outposts like El Merrie Del and the Fernando Ranger Sta are nestled at the mountain base, while Herreras Ranch and Selby Oaks mark the footprint of early residents. The terrain is deeply incised by a series of drainages, including Wildwood Canyon and Gold Canyon, which descend toward the Little Tujunga Canyon floor. The mapping of a high-altitude Firebreak and multiple tanks suggests an era intensely focused on watershed management and fire prevention. Water resources are further highlighted by landmarks such as Dexter Park Reservoir and the uniquely named Fascination Spring, illustrating how essential these mountain sources were for the developing communities below.
