2019 Map of Ruby B-4 SW

About this map

The Sulatna River meanders across this Alaskan interior landscape, creating a complex network of oxbow lakes and wetlands within the Ruby B-4 SW quadrangle. Located in the Yukon-Koyukuk Census Area, the terrain is defined by the winding course of the river as it flows generally westward, joined by smaller tributaries including Cottonwood Cr and Bonanza Cr. The map reveals a remote landscape largely devoid of permanent human settlements, with the geography organized according to the Public Land Survey System grids of T13S R20E and T14S R20E. The intricate drainage patterns and low-lying river valleys captured in this 2019 survey offer a precise look at the hydrology and topographical contours of the region before further natural shifts occur in the shifting river channels.
