1951 Map of Port San Luis

USGS Topo · Published 1953

About this map

Port San Luis serves as the coastal anchor for this mid-century topographic study, where the steep coastal bluffs of the San Luis Range meet the Pacific Ocean. This survey preserves the complex land tenure of the Cañada De Los Osos Y Pecho Y Islay land grant, showing a landscape defined by deep canyons such as Diablo Canyon, Coon Creek, and Islay Creek. The nautical importance of the region is evident at Point San Luis, where a Lighthouse and breakwater provide refuge. Inland, the terrain rises sharply to prominent peaks like Saddle Pk and Bald Knob, illustrating the difficult geography that kept this stretch of the Central Coast largely focused on maritime activity and ranching. Offshore hazards including Pecho Rock and Santa Rosa Reef are carefully charted, reflecting the integration of hydrographic data into the terrestrial survey.
