1948 Map of Sitka B-1

About this map

Admiralty Island's intricate coastlines are documented in this mid-century survey, revealing a landscape defined by deep fjords and tidal flats within the Tongass National Forest. The map detail centers on the complex waterways of Pybus Bay and Gambier Bay, where the transition from steep, high-elevation terrain to the sea is immediate. Numerous cabins are noted along the shoreline, particularly near Cannery Cove and the San Juan Islands, indicating the localized coastal activity of the era. The hydrography, compiled from earlier charts, highlights the West Channel and the Southwest Islands, illustrating the navigational challenges and sheltered harbors of the Alexander Archipelago. From Pybus Lake in the interior to the tidal flats of the bays, the sheet provides a precise record of the shoreline as it existed before contemporary environmental shifts.
