2017 Map of Acorn Flats

About this map

Acorn Flats defines this portion of the Montana high plains, where the Garfield Co Rosebud Co line divides the landscape into vast sections of open ranching country. The terrain is marked by significant erosion patterns, featuring Devils Canyon and various coulees such as Germo Coulee and Hanson Coulee that drain toward local watercourses. Sparse infrastructure is represented by a few key thoroughfares, including Acorn Flats Rd and Cohagon Rd, which provide access to remote properties like the one reached via Miller Ranch Ln. Water sources are critical in this arid environment, with Wilkes Spring serving as a vital landmark alongside Acorn Cr, Heist Cr, and Little Porcupine Cr. The map reflects the organized grid of the Public Land Survey System, illustrating how land ownership and agricultural use have been structured in this part of Rosebud and Garfield counties.
