2020 Map of Elkhorn Creek East

About this map

The tri-border region where South Dakota, Montana, and Wyoming converge is defined by a sparse network of seasonal drainages and vast public land divisions. This 2020 study highlights the intricate hydrology of the high plains, centered on the winding course of Elkhorn Cr as it traverses the boundary between Carter and Butte Counties. The map details the convergence of several small tributaries including Frozen Horse Cr and Bean Blossom Cr, which flow through a landscape of sharp relief and high-elevation ridges. The survey captures the intersection of three major state and county lines, providing a precise look at the township and range system that organized this portion of the northern plains. The lack of named settlements reflects the open, unpopulated character of the range along the South Dakota and Montana border.
