2021 Map of Joaquin Rocks

USGS Topo · Published 2021

About this map

Joaquin Rocks and the rugged Joaquin Ridge dominate this section of the Diablo Range in Fresno County. This 2021 topographic survey captures a landscape defined by sharp elevation changes and numerous natural water sources, including Rattlesnake Spring, Zalba Spring, and Joaquin Spring. The terrain is characterized by a series of deep canyons such as Horsethief Canyon and Portuguese Canyon, which drain into the Ragged Valley and toward the San Joaquin Valley edge. Access to these heights is traced through the Joaquin Rocks Lookout Rd and S Joaquin Ridge Lookout Rd. Other distinctive landmarks like Donut Rock, Black Mtn, and The Clearing provide orientation points across the complex topography of Anticline Ridge and the Big Blue Hills.
