2017 Map of Ophir D-4 SW

USGS Topo · Published 2017

About this map

Little Mud River winds through this interior Alaskan landscape, defining the hydrologic character of the Yukon-Koyukuk region. The waterway meanders extensively, creating a complex network of oxbow loops and abandoned channels that characterize the low-lying terrain. As shown in this 2017 U.S. Geological Survey record, the river system dominates the township boundaries of t19s r4e and t19s r5e, reflecting a wilderness environment where natural watercourses dictate the geography. The confluence of the smaller branch with the main Mud River in the eastern portion of the quadrangle illustrates the drainage patterns typical of this remote subarctic basin. For researchers or cartography enthusiasts, the map provides a precise look at the shifting fluvial morphology in a region largely defined by its untracked wetlands and river corridors.
