About this map

The Mustang Ridge San Andreas Rift Zone dominates this 1960s landscape, tracing the powerful geological divide through the interior of Monterey and San Benito Counties. This survey illustrates a complex network of deep canyons, including Griswold Canyon, Blair Canyon, and Tickner Canyon, which feed into the broader basins of Peachtree Valley and Long Valley.

Evidence of human management of this remote terrain is found at the Mustang Fire Control Station and the winding path of the Mustang Grade. The mapping of fence lines and localized water sources like wells and tanks reflects the area's agricultural and ranching utility during this era. Waterways such as San Lorenzo Creek and Lewis Creek dictate the local topography, carving paths between prominent landmarks like Monarch Peak and Cleveland Rock.
