1943 Map of Joaquin Rocks

About this map

Joaquin Rocks dominate the high terrain of western Fresno County, marking a rugged transition between the Cervo Hills and the floor of the San Joaquin Valley. This 1943 survey documents a landscape of large-scale ranching and early petroleum infrastructure during the early war years. Notable homesteads such as Lillis Ranch and Domengine Ranch are positioned near vital water sources like Domengine Spr, while the Mack Pumping Sta indicates the regional industrial activity in the foothills. The northern valley floor is largely open, punctuated only by the Cantua Sch and the intermittent flow of Cantua Creek. To the south, steep canyons like Nunez Can and Diaz Canyon carve through the Ridge, leading toward peaks like Black Mtn. The map preserves a moment when remote outposts like The Clearing and Jordan Ranch still served as primary landmarks in this high-desert environment.
