1973 Map of Lopez Pass

USGS Topo · Published 1981

About this map

Lopez Island and Decatur Island anchor this hydrographic and topographic study of the San Juan archipelago. In the early 1970s, the landscape shows a mix of protected conservation areas and early development, including the San Juan Islands National Wildlife Refuge protecting small landforms like Crab Island and Skull Island. Transportation is represented by a Landing Strip on Decatur Island and the corridor of Pavey Blvd on the larger Lopez Island landmass.
