Westport and the surrounding coastline of Mendocino County anchor this 2021 topographic record. The settlement pattern follows the rugged North Coast, where small communities like Rockport, Hardy, and DeHaven are connected by narrow roads winding through significant elevations. The terrain is defined by steep ridges, including Lincoln Ridge and Alviso Ridge, which drop sharply into the Pacific Ocean. Numerous drainages such as Wages Creek and Cottaneva Creek have carved deep valleys and gulches like Dodge Gulch and Slaughterhouse Gulch as they flow toward the sea.
