About this map

Port San Luis serves as the focal point of this coastal landscape, situated where the Irish Hills meet the Pacific Ocean. The geography is defined by a series of steep drainages cutting through the coastal range, including Diablo Canyon, Wild Cherry Canyon, and Rattlesnake Canyon. This 2015 topography reveals a sparsely developed shoreline dominated by natural landforms and technical access roads like Pecho Valley Rd and Diablo Canyon Rd.

Inland, the terrain rises sharply from the sea, carved by Coon Creek and Pecho Creek. The naming of features like Mine Canyon, Vineyard Canyon, and Harford Canyon suggests a history of varied land use, from resource extraction to agricultural attempts on the hillsides. Toward the eastern edge, the elevation climbs toward Tunnel Point, overseeing the maritime activities centered around the port infrastructure.
