2018 Map of Iliamna D-3 SE

About this map

Iliamna Lake anchors this corner of the Alaska Peninsula, where the landscape is defined by the drainage systems of the Pile River and the Iliamna River. This 2018 survey reveals a territory of significant transition, situated along the jurisdictional boundary of the Lake and Peninsula Borough Kenai Peninsula Borough. The presence of the Williamsport-Pile Bay Road indicates a vital portage corridor, connecting the northern reach of the largest lake in Alaska to the coastal waters of Cook Inlet to the east. Between the major river valleys, the terrain is dotted with smaller water bodies such as Long Lake, illustrating the complex glacial geography of the region. This map is an essential reference for understanding the modern infrastructure and natural boundaries in a remote area where transportation is governed by narrow overland routes and massive inland waterways.
