1973 Map of Lopez Pass

About this map

Lopez Island and Decatur Island define this coastal landscape where the Strait of Juan de Fuca meets the Rosario Strait. The intricate coastline is marked by deep inlets like Hunter Bay, Mackaye Harbor, and Watmough Bay, revealing a maritime environment of reefs and rocky outcroppings. Small landmasses such as Center Island, Ram Island, and Colville Island are scattered throughout Lopez Sound, several of which are protected as part of the San Juan Islands National Wildlife Refuge. On shore, the terrain rises to notable heights at Chadwick Hill, overlooking Watmough Head and the narrow passage of Lopez Pass. The presence of Gravel Pits and various light-duty roads like Pavey Blvd suggests a mix of local industry and recreational access, including sites like Agate Beach County Park and Castle Island State Park.
