2019 Map of Ruby B-3 NE

About this map

The Nowitna River dominates this interior landscape, winding in a complex series of tight oxbows and meanders through the Yukon-Koyukuk region. This environment is defined by its dramatic water-level shifts and shifting channels, where the main river body is joined by tributaries including the Little Mud River and Lost River. The map illustrates a largely uninhabited wilderness, structured primarily by the Public Land Survey System lines such as t11s r23e and t12s r24e. The dense contour lines in the eastern and southern portions of the quadrangle indicate significant elevation changes rising away from the river valley, providing a clear picture of the drainage patterns and topographic relief of this part of the Alaskan interior in the early twenty-first century.
