About this map

The coastal interface of the Tongass National Forest meets the Gulf of Alaska in this 2017 survey of the Yakutat region. The landscape is defined by an intricate network of wetlands and shifting waterways, most notably the Ahrnklin River and Middle Slough. These hydrologic features carve through the low-lying terrain, creating landforms such as Blacksand Island and the protective Blacksand Spit along the coast.

Navigational history is marked by the Dry Bay Canoe Trail, which threads through the marshes and along the inner banks of the spit. This route suggests a reliance on shallow-water transit through the Seal Creek drainage. The map's detail provides a look at the natural drainage patterns and coastal morphology of the borough before any significant modern development, preserved within the Tongass National Forest boundaries.
