Pacific Ocean waters dominate this maritime survey of the Aleutian island chain's northern reaches. This specific 2020 edition provides a focused look at an open marine corridor within the Pacific Ocean, where the absence of terrestrial features or coastal settlements reflects the vast maritime isolation of the False Pass C-3 SW quadrangle. The map is a dedicated navigational and hydrographic record of the open sea, documenting a segment of the North Pacific where only the deep water and the occasional grid of a modern topographic study mark the location.
