2014 Map of Timber Coulee South

About this map

Diamond Valley occupies the northwest portion of this landscape, set against the high ground of Teton Ridge and the dramatic relief of Timber Coulee. The terrain is defined by the sharp transition between level plains and deep drainages, with Rye Coulee cutting through the southwestern corner. This 2014 survey documents the modern layout of the Teton County and Chouteau County line, showing a rural grid of secondary roads like Dutton Rd E and MT-379 that navigate the ridges and depressions. The placement of these settlements and named geographical features suggests a land shaped by water erosion and agricultural necessity, where the coulees provide natural breaks in the vast Montana plains.
