About this map

Clay extraction and specialized institutions define the mid-century landscape around Ione, where numerous claypits and a firebrick facility signify a robust industrial footprint. The northern portion of the map is dominated by the sprawling grounds of the Preston School of Industry, an important regional landmark complete with its own Preston Reservoir and airstrip. The Southern Pacific rail line cuts through Ione Valley, serving smaller rail-side settlements like Dagon and Clarksona.

The southern reaches show the early stages of significant hydrological change, with blue hatching indicating the upcoming expansion of the Camanche Reservoir. This transitional period in Amador County is further illustrated by the presence of the Newton Mine and various quarries set against the rugged backdrop of the Buena Vista Peaks. Water features like Sutter Creek and Jackson Creek provide the primary drainage for this complex mix of industrial mining, ranching, and public works.
