USGS Topo · Published 2021About this map
Tongass National Forest defines the coastal character of this Kuiu Island landscape, where intricate shorelines and tidal inlets dominate the geography. The map tracks the vital transportation corridors of the region, including the Kuiu Mainline and the Threemile Arm Portage Trl, which connect deep-water access points like Seclusion Harbor and No Name Bay. This 2021 survey illustrates the reliance on maritime and forest service infrastructure in the Alexander Archipelago, showing how natural features like Eagle Island and the reaches of Upper 3-Mile Arm frame the navigable waterways essential for local transit and timber management.
