Knox Ridge dominates the northern reaches of this Fergus County landscape, a prominent upland that dictates the drainage patterns for the surrounding coulees. Watercourses such as Armells Cr and Sourdough Cr carve through the terrain, illustrating the complex erosion that defines this portion of Montana. The map reflects a region shaped by high ridges and deep draws, where transportation is limited to established routes like Knox Ridge Rd and Mabee Lonesome Rd.
