2021 Map of Lillis Ranch

About this map

Monocline Ridge and the Ciervo Hills define the western transition from the high Diablo Range down into the fertile floor of the San Joaquin Valley. This landscape is marked by the deep erosional cuts of Arroyo Hondo and Arroyo Ciervo, which give way to the more level agricultural expanses of the Central Valley. The presence of Green Water Spring and Sulphur Spring among the Big Blue Hills highlights the critical water sources that sustain life in this arid part of Fresno County. The Giffen Cantua Ranch stands as a prominent marker of the region's large-scale ranching and agricultural heritage, situated near the intersection of various ranch roads and the Coalinga-Mendota Rd. Drainage patterns like Cantua Cr and Salt Cr illustrate how seasonal water flows shaped the valley's alluvial geography.
