About this map

Unimak Island presents a rugged maritime landscape along the Aleutian chain, where the land meets the Pacific Ocean. This coastal section is defined by prominent topographical markers such as Scotch Cap and the offshore formation of Pinnacle Rock. The interior drainage is carved by numerous waterways, including the winding course of Big River, Mishap Cr, and Cap Cr. These features illustrate the raw geological forces at work on the island's southern shore. The map provides a precise view of the land-sea interface at this specific coordinates, capturing the intersection of tectonic and oceanic environments in the Aleutians East region.
