2021 Map of Petrolia

USGS Topo · Published 2021

About this map

Petrolia serves as the inland anchor of this coastal landscape, situated where the N Fork Mattole River meets the main stem of the Mattole River. The 2021 survey details a region defined by dramatic seaside landmarks and ridge systems, from the prominent Punta Gorda at the southern edge of Mattole Beach up to the distinctive Mussel Rock in the north. The area's complex geography is reflected in colorful local nomenclature, including Uncle Tommy, Shenanigan Ridge, and Johnny Jack Ridge. Researchers can trace the legacy of early ranching and coastal passage through family-named features like Moore Hill and Collins Gulch, alongside the winding Lost Coast Trl. Settlement patterns are concentrated along the river valley via Mattole Rd, while the higher elevations of Cooskie Mtn and Little Chaparral Mtn remain largely defined by natural contours and gulches like Jim Goff Gulch.
