2021 Map of Ortigalita Peak

About this map

Ortigalita Peak and the high elevations of the Diablo Range define this landscape where Merced, San Benito, and Fresno counties meet. This terrain is marked by a complex system of drainages, including the perennial and seasonal flows of Piedra Azul Cr and Ortigalita Creek, which carve deep passages such as Molina Canyon and Piedra Azul Canyon. Cattle ranching and land management are evident through the network of private tracks like Mc Creery Ranch Rd and Paul Negra Rd. The geography transitions from the elevated reaches of the Las Aguilas Mountains in the south down toward the Wisenor Flat and the edges of the San Joaquin Valley in the northeast. Water sources such as Piedra Azul Spring and Carranza Spring provided vital points of interest for early surveyors and land users in this arid, high-country environment.
