2019 Map of Medfra D-4 SW

USGS Topo · Published 2019

About this map

The Nowitna River meanders through this interior Alaskan wilderness, forming complex oxbows and marshy lowlands in the eastern portion of the quadrangle. This 2019 survey by the U.S. Geological Survey illustrates a landscape defined by water and topographic relief rather than human infrastructure, as no roads or settlements are recorded. The western edge is marked by the Susulatna River, while Meadow Cr drains the northeastern corner. These river systems represent the primary geographic orientation for the region, reflecting the natural drainage patterns of the Yukon-Koyukuk Census Area. The map provides a detailed view of the terrain within several townships, including t19s r20e and t20s r21e, showcasing the transition between high ridges and river valleys.
