2019 Map of Ruby B-1 NW

USGS Topo · Published 2019

About this map

Big Mud River winds through the northern reaches of this interior Alaskan landscape, marking the primary topographical relief in a region dominated by surveyed townships. The terrain is characterized by the structured grid of the Public Land Survey System, specifically detailing boundaries such as t11s r27e, t11s r28e, and t13s r27e. This 2019 survey documents the wild and undeveloped character of the Yukon-Koyukuk region, focusing on the intricate elevation changes and hydrology of the river basin. Without roads or permanent settlements recorded, the map emphasizes the natural drainage patterns and township divisions that define this remote section of the Alaskan wilderness.
