2021 Map of Unimak C-2 SW
USGS Topo · Published 2021About this map
Westdahl Peak anchors the southern portion of this topographical study within the Aleutian range, where steep volcanic slopes drop away toward the sea. The landscape is defined by the high-elevation contours of this active terrain, captured here in modern detail. Along the northern reaches, the Pogromni River drains the mountain's flanks, cutting through a remote and unpopulated expanse of the Aleutians East Borough. The map's detail focuses primarily on the dramatic elevation changes and natural drainage patterns of Unimak Island, illustrating the stark environmental forces that shape this part of the Alaska Peninsula.
