Petrolia and the surrounding coastline reflect a landscape shaped by early California resource extraction and the winding course of the Mattole River. The map highlights a significant historical landmark, the State Historical Mon 543 First Oil Field in California, marking the site of the state's first oil well. Settlement is concentrated along the river valley and the Mattole Road, while the rugged coastal interior is defined by massive landforms like Prosper Ridge and Shenanigan Ridge.
