2018 Map of Iliamna B-5 SW

USGS Topo · Published 2018

About this map

Katmai National Preserve occupies the southern reaches of this landscape, marking a transition into protected wilderness within the Lake and Peninsula Borough. The terrain is defined by dramatic elevation changes, with numerous unnamed peaks and ridges surrounding the basin of Gibraltar Lake in the northeastern corner. This freshwater body sits at the foot of steep slopes, serving as a primary hydrological feature in an area otherwise characterized by high-altitude glacial valleys and tundra. The map also delineates the administrative boundary with the Kenai Peninsula Borough, illustrating how these massive jurisdictional lines overlay the remote Alagnak River watershed region. Without roads or permanent settlements, the map focuses on the raw topography and the legal boundaries of the preserve, essential for understanding land management in the Alaska Peninsula's interior.
