Antelope Pass anchors this 2020 landscape in Valley County, Montana, where the terrain is defined by a network of seasonal drainages and coulees. The map highlights the high plains character of the region, featuring Lake Gable and the intricate flow of Upper Ichpair Cr and Bluff Cr. This is a landscape shaped by water erosion, as seen in the deep incisions of Starbuck Coulee, Harry Coulee, and Riggin Coulee, which create a complex topographical pattern typical of the Missouri River country drainage system.
