About this map

The Irish Hills dominate this coastal landscape of San Luis Obispo County, where steep canyons like Ruda Canyon and Diablo Canyon cut through the mountains toward the Pacific Ocean. At the northern edge, Montana De Oro State Park encompasses the settlement at Spooner and the drainage of Coon Creek. The coastline is marked by jagged seafaring hazards including Lion Rock, Double Rock, and the Santa Rosa Reef, reflecting the maritime importance of this stretch of the Central Coast.
