2017 Map of Ophir D-4 NW

About this map

Little Mud River winds through the northern reaches of this interior Alaskan wilderness, as documented in this 2017 study of the Yukon-Koyukuk region. The landscape is defined by the subtle rising elevations of the Flat Hills, where tight contour lines reveal a topography of drainage basins and ridges that feed the river system. The map serves primarily as a record of the Public Land Survey System divisions, clearly delineating townships and ranges such as t17s r5e and t18s r5e. With no roads or settlements indicated, the map captures the remote character of the Yukon-Koyukuk Census Area, focusing on the natural hydrography and the intersection of various township boundaries that define land ownership and management in this part of the state.
