2018 Map of Slack Canyon

About this map

The San Andreas Fault cuts a visible path through this portion of the Diablo Range, defining the tectonic character of the borderlands between Monterey and Fresno counties. The landscape is characterized by a series of parallel valleys and canyons, most notably Peachtree Valley and Indian Valley, which follow the northwest-southeast grain of the fault system. This 2018 survey reveals a terrain defined by its water sources, where numerous named springs such as Little Bitterwater Spring, Buckeye Spring, and Splitrock Spring provide vital points of interest in an otherwise arid environment.
