2021 Map of Ketchikan D-3 SE

About this map

Tongass National Forest lands dominate this coastal Alaskan landscape, where the saltwater of Walker Cove cuts into the southern edge of the sheet. The terrain is defined by its dramatic glacial carved valleys and drainage systems, including the S Fork Chickamin River in the north and the prominent King Cr that feeds through the central mountains. In the southwest, Gilbert Lake sits in an elevated basin, surrounded by a complex network of smaller tributaries like Choca Cr. This modern survey reflects a wilderness area without established roads or settlements, primarily used by the Alaska Dept. of Transportation and the Forest Service for resource management. The map serves as a primary record of the hydrological patterns of the Ketchikan Gateway Borough, detailing the relationship between mountain snowmelt and the coastal inlets of the Alexander Archipelago.
