2020 Map of Chignik B-7 SE

USGS Topo · Published 2020

About this map

Muddy River defines the landscape of this remote corner of the Aleutians East Borough, carving a braided path through a valley of glacial outwash and wetlands. This 2020 survey records the intricate shifting channels of the river system as it moves across the coastal plain of the Alaska Peninsula. The terrain is characterized by complex contour lines indicating small, scattered knolls and depressions within the broader floodplain, a pattern that reflects the dynamic hydrological history of the region. Though largely devoid of named human settlements or infrastructure, the map serves as a vital record of the natural topography and the expansive reach of the Muddy River before it nears the Pacific coast.
