Pacific Ocean waters dominate this maritime survey of the Aleutian Islands region, capturing a remote section of the Alaskan coastline in the early twenty-first century. This specific quadrangle covers a stretch of sea and land where the T66s R100w and T66s R101w townships meet, illustrating the intersection of the Public Land Survey System with the North Pacific. The lack of terrestrial settlements or landmarks emphasizes the isolation of this Alaskan maritime boundary. Researchers of maritime history or geographers tracking township and range boundaries like T65s-R100w will find the exact coordinates of this coastal expanse useful for identifying specific nautical and shoreline positions in the Aleutians East Borough.
