About this map

Hornitos serves as the focal point of this post-war landscape, situated amidst the complex terrain of western Mariposa County. The map documents an area deeply defined by its extraction history, evidenced by a dense network of operations like the Mt Gaines Mine and Red Cloud Mines. The rural infrastructure of the late 1940s is preserved here, featuring the Quartzburg Sch and scattered homesteads such as Williams Ranch.

Tracing the path of Cotton Creek and Burns Creek toward the rising waters of Lake Mc Clure, the survey illustrates how the environment transitions from the peaks of Mariposa Mountain to the reservoir's edge. Notable landmarks like Williams Peak and the remote Hell Hollow underscore the geographic isolation of these foothill settlements during an era of significant regional water management and mining transition.
