Forest Falls and Valley of the Falls sit deep in the Mill Creek Canyon, serving as central points of settlement within the San Bernardino National Forest. This 1990s revision reveals the geographic importance of the Washington Monument (Original Initial Point) on the northern ridge, a primary surveying marker for the region. The landscape is defined by massive elevation shifts between peaks like San Bernardino East Peak and the residential enclaves at Mountain Home Village. South of the Yucaipa Ridge, the map tracks the development of Oak Glen, known for its agricultural history and the Oak Glen Conservation Camp. Infrastructure for water and power management is visible through labels for a Powerhouse, Diversion Dam, and an aqueduct, supporting the communities established along the canyon floors.
