2021 Map of Unimak C-1 SW
USGS Topo · Published 2021About this map
The Pacific Ocean coastline dominates this 2021 topographic study of the Aleutians East Borough, where the land meets the sea at Unimak Bight. The terrain is characterized by steep, closely spaced contour lines descending from the north toward the shore, revealing the dramatic elevation changes typical of Alaska's volcanic islands. Surveyed across townships including t64s r100w and t65s r101w, the map shows a landscape largely shaped by natural forces rather than human development. The coastal interface at Unimak Bight serves as a primary reference point for the maritime and ecological boundaries of this remote stretch of the Aleutian chain.
