2020 Map of Chignik A-7 SE

USGS Topo · Published 2020

About this map

The Aleutian Range dominates this landscape in the Aleutians East Borough, where steep topographic contours reveal the dramatic rise of the volcanic peninsula. This high-altitude terrain serves as a critical drainage divide for local waterways, most notably the Spirit River in the northeast and the Milky River in the southwest. The mapping of the township and range lines, including t47s r70w, t47s r69w, t48s r70w, and t48s r69w, provides a structural framework for this otherwise unpopulated wilderness. The glacial or snow-fed character of these river systems is typical of the region, where the network of smaller streams and unnamed lakes feeds into these larger glacial arteries.
