1962 Map of Copperopolis

About this map

Copperopolis serves as the focal point of this Mother Lode landscape, surrounded by a legacy of hard-rock mining defined by the Skyrocket Mine and Quail Hill Mine. The area's transition from a mining frontier to a managed water and ranching region is visible through the expansive Rancho Del Estanislao and the infrastructure of the Hetch Hetchy Aqueduct. Significant water features like the Stanislaus River, Tulloch Lake, and Melones Reservoir dominate the eastern reaches, while the historic river crossing at Knights Ferry marks a vital connection point. The map also captures the path of the Sierra Railroad and numerous historic landmarks, including the O'Byrne Ferry Hist Mon, providing a detailed view of the industrial and transportation networks that shaped Calaveras and Tuolumne counties.
