1973 Map of Sucia Island

About this map

Patos Light stands as a sentinel at the northern edge of the San Juan archipelago, marking the transition between Boundary Pass and the Strait of Georgia. This maritime landscape is defined by the unique geological formations of Sucia Island, where a horseshoe-shaped series of ridges encloses Echo Bay. The map documents the protected lands of Sucia Island State Park and Patos Island State Park, highlighting numerous campgrounds that cater to the region's seafaring visitors. Shoreline details like Fossil Bay, Shallow Bay, and Fox Cove illustrate the intricate coastline and natural harbors used by mariners. Beyond the main landmasses, smaller features such as North Finger Island, South Finger Island, and the Cluster Islands form part of the San Juan Islands National Wildlife Refuge, preserving the area's ecological character.
