About this map

Port San Luis serves as the focal point of this coastal survey, where maritime activity meets the steep rise of the Irish Hills. The coastline is defined by hazardous features and industrial sites, notably Diablo Canyon and the prominent Point San Luis. Off the shore, a series of rocky outcrops including Whalers Island, Smith Island, and Pecho Rock dot the Pacific Ocean, while the built environment is marked by Harford Pier and the structure at Tunnel Point.

Inland, the topography transitions quickly from the sea to significant elevations such as Saddle Peak Mount Buchon and Green Peak. Deep drainages like Ruda Canyon and Rattlesnake Canyon carve through the coastal range, illustrating the drainage patterns that feed into the sea. This 2012 data shows the modern road network, including See Canyon Rd and Davis Canyon Rd, which provide access to the remote ridges and springs like Glenrose Spring.
