1951 Map of Sitka D-3

About this map

Chichagof Island and Admiralty Island face one another across the wide expanse of Chatham Strait in this early 1950s survey. The map details a landscape of rugged maritime industry and wilderness, most notably at the site of Gypsum (Abandoned) on the western shore. This location, situated near the tidal flats of Gypsum Creek, represents the remains of early 20th-century mining activity that once drove the local economy before the site was left to the elements.
