Hepsedam Peak and the high ridges of the Diablo Range define this landscape along the border of San Benito and Monterey counties. The path of the San Andreas Fault cuts through the southwestern corner, shaping the orientation of Mustang Ridge and the drainages of Beeman Canyon and Yaqui Canyon. Water is a defining element in this arid environment, evidenced by the presence of Hernandez Reservoir to the north and numerous small water sources like Hepsedam Spring, Cottonwood Springs, and Mud Trail Pond. To the west, the flat expanse of Spanish Flats sits beneath the prominent Vasquez Rock, while the San Benito River winds through the Hernandez Valley before entering The Gorge. This map captures a sparsely populated region of California, where the land is primarily characterized by its geological complexity and the network of canyons and gulches like Rattlesnake Gulch and Horsethief Canyon that drain into the central valley.
