About this map

The Merced River and Tuolumne River dominate this Central California landscape, where the foothills of the Sierra Nevada meet the irrigation-rich valley floor. The Yosemite Valley RR follows the southern riverbank through Merced Falls and Exchequer, a critical transportation link for the region's timber and minerals before mid-century reservoir expansions. In the north, the Don Pedro Reservoir is already a prominent feature, surrounded by legacy mining operations such as the Fortynine Mine, Solambo Mine, and Buzzard Roost Mine.

Lower elevations show the development of early water management systems, including the Modesto Canal and North Side Canal, which support settlements like Snelling and Hopeton. For genealogists and local historians, the map preserves the locations of rural infrastructure like the Granite Spring Sch and named crossings like Basso Bridge. This 1944 edition reflects the area's transition from gold-rush era mining to a modern hydraulic and agricultural economy.
