About this map

Kuiu Island, an expansive landmass within the Tongass National Forest, dominates this coastal survey of Southeast Alaska. The landscape is defined by the intricate shoreline of Seclusion Harbor and the northern reach of the Gulf of Alaska. Navigational routes across the island's timbered interior include the Kuiu Mainline and the historic Threemile Arm Portage Trail, which provides a vital overland link between coastal inlets. The map illustrates a remote wilderness managed for natural resources, where the topography transitions from sea-level coves to the high ridgelines of the Alexander Archipelago. Sparse infrastructure is limited to these established forest trails and logging roads, reflecting the region's focus on conservation and industrial forestry in the early 21st century.
