1955 Map of Monocline Ridge

About this map

The crest of Monocline Ridge dominates this 1955 survey, revealing the high-elevation transition from the foothills of the Coast Ranges down into the irrigation-dependent flatlands of the Central Valley. Infrastructure is the primary story here, shown through the massive California Aqueduct slicing through the northeast corner and a series of heavy industrial lines, including several marked Pipeline. Settlement is sparse, anchored by the Chaney Pumping Station at the junction of Dinuba Avenue and Newcomb Avenue. The land's utility is further marked by a series of Prospect sites and Water Tanks (Abandoned) in the rugged drainages of Tumey Gulch, suggesting an era of shifting water needs and mineral exploration. Significant updates from 1971, shown in purple, capture the expansion of the regional road network along Manning Avenue and Floral Ave.
