2018 Map of Iliamna A-5 SW

About this map

Katmai National Park and the adjacent Katmai National Preserve define this landscape on the Alaska Peninsula. The map reveals a transition from the elevated peaks of the Walatka Mountains in the southwest to a complex hydrological network of glacial lakes and drainages. Notable water bodies including Iron Springs Lake, Battle Lake, and Pirate Lake dominate the central and southern portions of the quadrangle. These features, along with Moraine Cr and Crevice Cr, suggest a terrain primarily shaped by ancient ice movements and seasonal meltwater. The placement of the Lake and Peninsula and Kenai Peninsula Borough boundary line through this remote wilderness highlights the administrative divisions that persist even in protected conservation lands. This 2018 survey provides a modern look at a region where natural drainage patterns dictate the geography of the Alaskan interior.
