About this map

Phoenix Lake and the nearby Phoenix Reservoir serve as central points in this landscape of the Sierra Nevada foothills. This 2018 survey reveals a terrain defined by both its gold-mining history and modern residential growth, where suburban developments like Mono Vista and Belleview sit adjacent to the steep canyons of the S Fork Stanislaus River. The legacy of 19th-century resource extraction is evident in the presence of the Sonnet Mine and roads like Shanghai Mine Rd and Remington Mine Rd.

The northeastern portion of the map is dominated by the Stanislaus National Forest, featuring prominent ridges such as Contention Ridge and Star Ridge. Significant water infrastructure, including the Columbia Ditch and a complex network of gulches like Hardscrabble Gulch and Rattlesnake Gulch, illustrates the region's long-standing relationship with water management for both mining and local utilities.
