1952 Map of Ruby B-3

About this map

Nowitna River meanders sharply through this Interior Alaska landscape, creating a complex network of oxbows and wetlands in the northeast corner of the quadrangle. Collected from aerial photography taken in the early 1950s, the map documents a transition from the low-lying basin of the Little Mud River to the prominent elevations of the Monzonite Hills in the west. This region, part of the Fourth Judicial Division, represents a largely roadless wilderness where the watercourses serve as the primary geographical markers. The intricate drainage patterns and contour data provide an essential record of this remote terrain before modern changes, illustrating the natural state of the Yukon-Koyukuk region during the mid-century period.
