The Pecho Luis Range dominates this late-nineteenth-century coastal survey, where the rugged terrain of the San Miguelito land grant meets the Pacific. At the southern tip of this coastal ridge lies Port Harford, a vital maritime gateway for the region. The map highlights the navigational infrastructure of the era, including the L.H. at Pt. San Luis and several prominent offshore landmarks like Pecho Rock and Whaler Id.. Numerous canyons, such as Diablo Canyon and See Canyon, cut through the hills, illustrating the natural drainage patterns that shaped early access to the interior. The presence of Mine Canyon suggests the early industrial interests that shared this landscape with traditional ranching and maritime commerce. This survey captures the transition of the San Luis Obispo coast from a series of isolated canyons into a structured maritime district.
