2017 Map of Ophir D-4 NE

USGS Topo · Published 2017

About this map

The Tlatl Hills rise above a landscape defined by the winding paths of the Mud River and the Little Mud River in this interior Alaska quadrangle. This 2017 study captures a remote portion of the Yukon-Koyukuk Census Area, where elevation contours reveal a series of ridges and valleys northwest of the riverbeds. The drainages show complex meandering patterns through the lower terrain, illustrating the hydrologic activity typical of the region. Free of developed settlements or road infrastructure, the map serves as a primary record of the topographic character within several townships, including t17s r6e and t18s r7e. It provides a clear view of the natural relief and waterway systems before any modern human encroachment or industrial footprint.
