2023 Map of Valdez C-4 SW

About this map

The Tonsina River defines the drainage of this interior Alaskan landscape, winding through a corridor of significant elevation changes. This modern survey illustrates the rugged hydrological network where the river meets the Tonsina Lake outlet, a critical geographic marker for navigation and local transit. The map documents the Tonsina Lake Trl as it skirts the northern bank of the river, providing the primary overland access through this remote territory. Several significant tributaries, including Rainbow Creek, Quartz Creek, and Squirrel Creek, are shown in high detail as they feed into the main river system. This map is essential for understanding the contemporary topography and watershed patterns in the Valdez region, particularly for those tracing access routes along the river valley.
