About this map

The Santa Lucia Range dominates this portion of San Luis Obispo County, where the landscape is defined by a dense network of watercourses and high peaks. The presence of the Oceanic Mine along the upper reaches of Santa Rosa Creek points to the area's industrial history, likely focused on quicksilver extraction common to this region of the Coast Ranges. Transportation is concentrated along Santa Rosa Creek Road, which follows the natural grade of the canyon toward the coast.

Local education and landmarks are anchored by the Mammoth Rock Sch and the geological formation Mammoth Rock. The southern portion of the sheet transitions into the San Geronimo area, with various drainages including Villa Creek and Cottontail Creek cutting through the terrain. This document reflects a mid-century landscape captured by the Army Map Service and later updated to show woodland cover through the late 1970s.
