2019 Map of Sutwik Island D-5 SW

About this map

The Aniakchak National Preserve defines this landscape on the Alaska Peninsula, centered on the dramatic hydrology of the Aniakchak Wild and Scenic River. Flowing southward from the interior, the Aniakchak River meanders toward its outlet at Aniakchak Bay in the southeastern corner of the quadrangle. The terrain is marked by the prominent landform of Cape Horn, which overlooks the river's path as it cuts through the coastal mountains. This 2019 survey documents a wilderness area largely defined by its natural boundaries and township lines, including t39s r52w and t40s r52w, showing the remote coastal interface where northern streams meet the tide. Small tributaries like W Cr drain the high ridges, illustrating the complex drainage patterns of this protected watershed.
