2017 Map of Sitka D-6 SW

About this map

Lisianski River and the surrounding drainage basins of the Tongass National Forest dominate this 2017 survey of the Southeast Alaska wilderness. The map documents a landscape defined by extreme relief and glacial topography, where the Steelhead River and Granite Cr cut through steep mountain corridors. Unlike many maps of this era that show human development, this sheet illustrates a nearly untouched coastal rainforest environment within the Unorganized Borough. The absence of roads or settlements emphasizes the remote nature of these watersheds, which are primary features for understanding the hydrology and land management boundaries of the Alexander Archipelago. Researchers can trace the fine-grained contour intervals that delineate the complex ridges and valley floors that characterize this protected forest land.
