2020 Map of Chignik C-4 SW

USGS Topo · Published 2020

About this map

The Alaska Peninsula serves as the backdrop for this 2020 survey, where the landscape is defined by its complex network of watercourses and topographical transitions. The Unangashak River meanders through the northeastern sector of the quadrangle, while several smaller tributaries, including Blueberry Cr and Fireweed Cr, drain the central and southern reaches. This territory marks a political boundary between the Aleutians East Borough and the Lake and Peninsula Borough, a line that bisects the map vertically.
