The T69s R70e and T69s R71e land survey boundaries define this coastal section of Southeast Alaska, where the landscape is almost entirely dominated by the waters of the North Pacific. The presence of the Public Land Survey System (PLSS) grid lines across the open water reflects the administrative mapping of the Prince of Wales-Hyder Census Area, even in reaches where no landform is present. This 2018 survey emphasizes maritime coordinates and jurisdictional boundaries over terrestrial features, serving as a clean cartographic record of the region's marine extent and the precise limits of its township and range divisions.
