1958 Map of Unimak B-2 NE

About this map

Cape Lutke projects into the northern waters of the Pacific Ocean in this mid-century hydrographic study of Unimak Island’s coast. Compiled by the Army Map Service using data from the late 1930s and early 1940s, the map provides precise soundings in fathoms along a coastline defined by rocky outcroppings and sand bars. The interior landscape, situated within the Third Judicial Division, is represented by detailed contour lines that reveal a steep, rising terrain characteristic of the Aleutian chain. This specific survey was not field-checked, relying instead on coastal hydrography from the U.S. Coast and Geodetic Survey to chart the treacherous shoreline where the volcanic slopes meet the sea.
