2018 Map of Table Mountain A-4 SW

About this map

The Sheenjek River meanders through this remote Arctic landscape, carving a wide valley floor defined by intricate drainage patterns and expansive alluvial flats. This 2018 survey by the U.S. Geological Survey captures the terrain where the river's path is joined by northern tributaries like Eskimo Cr from the east and Monument Creek from the west. The topography is dominated by the high ridgelines of the eastern Brooks Range, with elevation contours revealing the steep transition from the river valley to the surrounding peaks. The map provides a detailed look at the hydrology of the Yukon-Koyukuk region, illustrating how seasonal water flow shapes the permafrost-underlain ground through complex braided channels and scattered wetlands.
