1951 Map of Port San Luis

USGS Topo · Published 1964

About this map

Port San Luis anchors the southern edge of this coastal survey, where the maritime landscape of San Luis Bay meets the dramatic rising slopes of the San Luis Range. At the point, a Lighthouse stands as a vital navigational aid above the hazardous offshore features including Lone Black Rock and Santa Rosa Reef. The inland terrain is defined by complex drainage systems such as Wild Cherry Canyon and See Canyon, while high points like Saddle Pk and Bald Knob dominate the northern skyline. A single Mine indicates the area's geological and industrial activity during the mid-20th century, located among the steep ridgelines. The coastal stretch between Whalers Bay and Coon Creek remains largely undeveloped, preserving the original land grants and natural shoreline as they existed prior to late-century expansion.
