About this map

Mountain Home Village and Forest Falls anchor the high-altitude landscape of the San Bernardino National Forest as it appeared in the early 1970s. This survey marks the critical Washington Monument (Original Initial Point), the surveyor's anchor for the San Bernardino Meridian. The complex hydrology of the region is evident in the path of the Yucaipa Aqueduct and the presence of the Pine Powerhouse in the southern canyon lands.

Smaller settlements and agricultural outliers like Oak Glen and Mile High Ranch are documented alongside specialized facilities such as the Oak Glen Conservation Camp. The terrain is defined by steep drainage systems including Mill Creek Canyon and Banning Canyon, punctuated by landmarks like Monkeyface Falls and the Palisade Sch in the Forest Falls valley. These features illustrate a period of managed forest use where recreational sites like Big Falls Campground coexisted with vital water management infrastructure.
