2018 Map of San Gregorio

About this map

Martins Beach and the high bluffs of Mussel Rock define this coastal stretch of San Mateo County, where the Santa Cruz Mountains meet the Pacific Ocean. This modern survey illustrates a landscape shaped by narrow canyons and coastal terraces, with Tunitas Creek and San Gregorio Creek cutting through the terrain toward the shore. The interior is marked by a network of historic routes like Stage Rd and Tunitas Creek Rd, which navigate the steep elevations of Gordon Ridge and Round Hill. Further south near the town of Pescadero, the map identifies local landmarks essential for genealogical research, including Saint Anthony Cem and Mount Hope Cem. The presence of several distinct gulches, such as Dairy Gulch and Tahana Gulch, suggests the intricate drainage patterns that have historically dictated land use and road placement in this rural coastal region.
