2016 Map of Valdez B-5 NE

About this map

Tonsina Lake dominates the upper eastern reaches of this interior Alaskan landscape, serving as a primary hydrologic feature within the copper-river drainage system. The drainage pattern is defined by the Tonsina River, which flows southward from the lake, joined by tributaries such as Hurtle Cr and Greyling Cr. The topography is marked by significant elevation changes, as indicated by the tight contouring around the river valley and surrounding peaks. This 2016 survey documents the region's wilderness character, where the lack of roads or established settlements emphasizes the dominance of natural watercourses and glacial terrain. The map serves as a record of the shifting hydrography in the Unorganized Borough, where the interaction between mountain runoff and the larger lake system continues to shape the valley floor.
