2020 Map of Unalaska D-2 SW

About this map

Cape Cheerful dominates the southwestern corner of this maritime landscape, where steep coastal terrain meets the vast expanse of the Bering Sea. This coastal point represents the only significant landmass on an otherwise oceanic sheet, which primarily documents the hydrography and bathymetric features of the Aleutian coastline. Further offshore, the Chelan Bank marks a shallow underwater feature of interest to navigators and those studying the maritime geography of the Aleutians West Census Area. The map provides a precise record of these shoreline contours and underwater banks as they were surveyed in 2020.
