2020 Map of False Pass B-4 SE

USGS Topo · Published 2020

About this map

Pacific Ocean waters dominate this 2020 survey of the False Pass B-4 SE quadrangle in the Aleutians East Borough. The map is a rare example of a maritime-focused topographical sheet where no terrestrial landmarks or bathymetric contours are documented. According to the U.S. Geological Survey margin notes, elevation data for this specific area did not meet accuracy requirements, resulting in a minimalist representation of the open sea at the 1:25,000 scale. The map serves as a precise coordinate reference for this remote maritime corridor within the Aleutian chain.
