1989 Map of Cape Mendocino

About this map

Humboldt Redwoods State Park and the towering King Range dominate this coastal landscape where the land meets the deep waters of the Pacific Ocean. This topographic-bathymetric study reveals the dramatic transition from terrestrial peaks like Grasshopper Mountain and Taylor Peak to the massive underwater features of the Gorda Escarpment and Mendocino Ridge. Along the shoreline, navigational history is anchored by the Cape Mendocino Lighthouse and the Punta Gorda Lighthouse. Small settlements including Petrolia and Shelter Cove are positioned along the river systems of the Mattole River and Bear River, while the northern edge of the map shows the community of Rio Dell near the Eel River. The map also delineates the Cape Mendocino Coast Guard Reservation, illustrating the strategic importance of this westernmost point of California.
