2018 Map of Middleton Island D-1 SW

About this map

The Gulf of Alaska dominates this 2018 nautical and land survey, which documents a section of the maritime approaches south of the Alaskan mainland. The map is defined primarily by its open water, serving as a record of the vast coastal shelf within the Gulf of Alaska during the early 21st century. One of the few human navigational markings present is a designated Ferry Route that cuts across the northwestern corner of the quadrangle, illustrating the vital maritime transit corridors that connect remote Alaskan outposts. The inclusion of the t23s r6e township and range boundary indicates the formal extension of the Public Land Survey System even into these primarily aquatic zones.
