2016 Map of Nabesna A-2 NW

About this map

The Alaska Range provides the high-altitude backdrop for this portion of the Wrangell-Saint Elias National Preserve, where the landscape is defined by a dense network of glacial and snow-fed drainage systems. High-relief topography dominates the quadrangle, with elevation contours illustrating the steep descent from interior peaks toward the Chisana River in the northwest and Sheep Creek to the east. The map records the complex hydrology of the region, tracing the paths of numerous named tributaries including Sweetwater Cr, Sargent Cr, and Chavolda Creek. The boundary between the Valdez-Cordova and Southeast Fairbanks Census Areas bisects the terrain, highlighting the remote administrative divisions within this largely roadless wilderness. This survey is particularly useful for understanding the natural water courses before modern shifts in glacial melt affected local stream flow.
