2017 Map of Tanana B-2 SW

About this map

Rampart Gorge dominates the northwestern corner of this interior Alaska landscape, where the mighty Yukon River carves through high, steep-sided terrain. This 2017 survey illustrates a wild and unpopulated reach of the Yukon-Koyukuk Census Area, defined by a complex drainage network including Stevens Cr and Texas Cr. The map's contour lines reveal the dramatic verticality of the gorge and the surrounding ridges, which drop sharply toward the riverbank. To the east, Fish Cr meanders through lower elevations, showing the variation between the river's main canyon and its smaller tributaries. This sheet provides a clear look at the topographic character of the Alaskan interior, where the lack of roads or established settlements emphasizes the dominance of the river systems and raw geological formations.
