Blakely Island and Decatur Island define this nautical landscape in the San Juan archipelago, dominated by saltwater channels and mountainous island interiors. The map details a period of late-century conservation and sparse settlement, highlighting the San Juan Islands National Wildlife Refuge and large protected areas like Spencer Spit State Park. Interior water bodies such as Horseshoe Lake and Spencer Lake sit high above the surrounding Rosario and Lopez Sound, while human infrastructure is limited to small settlements at Thatcher, Olga, and Decatur.
