About this map

The Yakutat Foreland dominates this coastal survey, where the glacial outwash of the Tongass National Forest meets the sea. This landscape is defined by its massive braided river systems, including the Dangerous River, Ahrnklin River, and Italio River, which spill into the Gulf of Alaska through vast Tidal Flats. A barrier system formed by Blacksand Island and the long Blacksand Spit creates a complex network of lagoons and sloughs, such as Middle Slough, along the shoreline.

Evidence of mid-century industrial exploration appears near the coast, notably an Oil Well and an adjacent Landing Strip south of the Dangerous River. Several Cabins and a lone Cabin are scattered near the river mouths, suggesting seasonal use of these rich waterways. The intricate patterns of Seal Creek and the Antler River illustrate a dynamic environment of shifting sands and tidal influence before the modern era of coastal management.
