1996 Map of Blackburn Canyon

USGS Topo · Published 1999

About this map

Cranston sits at the confluence of the San Jacinto River and its northern fork, marking a focal point where water and early transportation routes converge in the San Jacinto Mountains. The landscape is defined by the steep elevation changes between Blackburn Ridge and Rouse Ridge, punctuated by seasonal springs like Alvin Spring and the aptly named Halfway Spring. This terrain reflects the complex management of public and private interests in the late twentieth century, showing the boundaries of the San Bernardino National Forest alongside the San Jacinto Viejo Grant and the San Jacinto Game Refuge. A Gaging Station on the river and a Communication Facility atop Red Mountain underscore the technical infrastructure necessary for monitoring and maintaining this drainage basin. The map traces the winding paths of the Toll Road and Rouse Hill Road, providing a detailed look at the access points used by foresters and early travelers through Bautista Canyon.
