2019 Map of Mount Katmai D-4 NW

About this map

Katmai National Preserve and Katmai National Park divide this wilderness landscape, marking a critical boundary in the Lake and Peninsula Borough. The transition between these two federal jurisdictions is defined by the expansive waters of Nonvianuk Lake in the north and the winding course of American Creek as it drains the interior highlands. Further south, the map identifies Hammersly Lake, situated near the edge of the survey area. This 2019 survey documents the hydrologic patterns and topography of a region dominated by glacial lakes and significant drainage systems, where the terrain rises from the shoreline into the upland interior. The absence of roads or permanent settlements underscores the isolation of these protected lands during the early 21st century.
