The Lost Coast is a mostly natural and development-free area of the California North Coast in Humboldt and Mendocino Counties, which includes the King Range. It was named the "Lost Coast" after the area experienced depopulation in the 1930s. In addition, the steepness and related geotechnical challenges of the coastal mountains made this stretch of coastline too costly for state highway or county road builders to establish routes through the area, leaving it the most undeveloped and remote portion of the California coast. Without any major highways, communities in the Lost Coast region such as Petrolia, Shelter Cove, and Whitethorn are isolated from the rest of California.
The region lies roughly between Rockport and Ferndale. At the south end, State Route 1, which runs very close along the coast for most of its length, suddenly turns inland at Rockport before merging with U.S. Route 101 at Leggett. At the north end, State Route 211 begins its journey at Ferndale, heading towards Highway 101 in Fernbridge. still says that "Route 211 is from Route 1 near Rockport to Route 101 near Fernbridge", but it is unlikely that the portion south of Ferndale will be built. Most of the region's coastline is now part of either Sinkyone Wilderness State Park or King Range National Conservation Area.
The Lost Coast consists of undivided Cretaceous marine metasedimentary and sedimentary rocks of the North American Plate steeply uplifted by Mendocino Triple Junction interactions with the Pacific Plate and Gorda Plate. The Lost Coast includes Tertiary marine sedimentary formations north of the Mattole River and a portion of the Franciscan Assemblage called Point Delgada at Shelter Cove. The steepness of uplift has created a coastal ridge forming a drainage divide parallel to the coast. The drainage pattern between Usal Creek and the Mattole River is a series of short streams with steep channel gradients.
