USGS Topo · Published 2019About this map
The Little Mud River winds through this interior Alaskan landscape, defining the hydrology of the Yukon-Koyukuk region as it appeared in the early 21st century. The map highlights a remote wilderness environment where water systems dictate the topography, illustrating the intricate drainage patterns of the river as it flows through several townships including t7s r27e and t7s r26e. This 2019 survey provides an essential record for researchers studying the natural evolution of the Alaskan interior, showing a terrain largely undisturbed by modern infrastructure and dominated by the shifting course of the Little Mud River and its associated wetlands.
