2023 Map of Valdez A-3 NW

About this map

The Chugach National Forest encompasses the southern reaches of this landscape, where steep high-altitude terrain meets the drainage basins of the interior. The topographic detail follows a network of alpine water systems, most notably the Tiekel River which flows across the northern edge of the sheet. Further south, the remote paths of Thunder Creek and Cleave Creek cut through deep relief, illustrating the natural drainage patterns of this unpopulated wilderness area. This 2023 survey clarifies the administrative boundary between Copper River County and Chugach County, a line that traverses the center of the quadrangle. The lack of roads or human-built structures emphasizes a landscape defined entirely by its hydrology and elevation, serving as a primary record of the glacial and riverine morphology that shapes this portion of Alaska.
