2023 Map of Valdez B-4 NE

About this map

The Alaska Pipeline snakes through this high-elevation corridor of the Copper River Census Area, following a path roughly parallel to the Richardson Highway. This modern survey reveals how the infrastructure of the North Slope oil transport interacts with the natural drainage basins of the Chugach Mountains. In the northern reaches of the map, the Little Tonsina River and its tributaries carve through the terrain near Tonsina, while further south, the Tiekel River and Fiftynine Mile Creek define the watershed. The map records a landscape largely defined by its watercourses and transit arteries, including several named paths such as the Fourth of July Creek Trl and the 54 Mile Trl. These routes, alongside drainages like Slate Creek and Fall Creek, emphasize the region's character as a vital yet sparsely inhabited passage through the Alaskan interior.
