USGS Topo · Published 2021About this map
Frederick Sound dominates this coastal maritime expanse in Southeast Alaska, where the vast waters meet the southernmost reaches of the Hoonah-Angoon Census Area. The most prominent terrestrial feature is Turnabout Island, a small landmass situated within the protected boundaries of the Tongass National Forest. This 2021 survey illustrates the modern administrative lines and maritime boundaries of the Alexander Archipelago, marking the intersection of the Prince of Wales-Hyder Census Area with neighboring jurisdictions. The map serves as a primary record of the hydrography and public land survey system divisions in a region defined by its reliance on water routes and federal forest management.
