2020 Map of Chignik A-3 SW

About this map

Aleutian Range topography dominates this remote Alaskan landscape within the Lake and Peninsula borough. The 2020 survey documents the complex glacial and volcanic landforms of the region, emphasizing the dramatic elevation changes and sharp ridgelines typical of the peninsula's spine. In the southern corner of the sheet, the waters of Ivan Bay meet the coastline, providing a critical geographic anchor for the surrounding wilderness. The map is primarily a study of natural relief and hydrography, showing a terrain largely defined by its absence of permanent infrastructure, roads, or settlements. The PLSS grid markings, including t48s r62w and t47s r61w, provide the only administrative framework across these mountainous reaches.
