1970 Map of Forest Falls

USGS Topo · Published 1988

About this map

Forest Falls and Valley of the Falls serve as the primary mountain communities in this 1970s survey, situated along the steep drainage of Mill Creek Canyon. This landscape is defined by its transition from the settled canyon floors to the high peaks of the San Bernardino Wilderness, including San Bernardino Peak and Anderson Peak. A notable historical marker, the Washington Monument, identifies the intersection of the San Bernardino Base Line and the San Bernardino Meridian, the foundational survey lines for Southern California. In the southern portion of the map, the agrarian and conservation character of Oak Glen is visible, featuring the Oak Glen Conservation Camp and Mile High Ranch. Infrastructure like the Pine Powerhouse and several water tanks trace the management of mountain runoff through the San Gorgonio River and Banning Canyon.
