2019 Map of McGrath B-4 SW

USGS Topo · Published 2019

About this map

Big River dominates this remote Alaskan landscape, winding through a network of wetlands and shifting channels within the Yukon-Koyukuk Census Area. This 2019 survey documents a region largely defined by its natural hydrology, where the river's wide floodplain creates a complex mosaic of ponds and small water bodies. The terrain reflects the characteristic drainage patterns of the Alaskan interior, showing how the waterway shapes the surrounding topography across several townships including t26n r31w, t26n r30w, t25n r31w, and t25n r30w. For those studying the evolution of Alaskan water systems, the map provides precise data on the river's path and the elevation profiles of the adjacent lowlands during the early twenty-first century.
