1923 Map of Monocline Ridge

USGS Topo · Published 1928

About this map

The dramatic geological formation of Monocline Ridge dominates this 1921 survey of western Fresno County, showcasing the complex topography where the Tumey Hills meet the valley floor. Early petroleum infrastructure is evident at the Oil Pumping Station, a testament to the region's developing industrial base during the early twentieth century. Education for the era's rural ranching families was centered at the Tumey Gulch School, located near the intermittent drainage of Tumey Gulch. This map provides a high-resolution look at the section lines and township boundaries that defined land ownership in this arid landscape before modern intensive irrigation transformed the surrounding plains.
