2017 Map of Antelope Pass

About this map

Antelope Pass anchors this 2017 survey of north-central Montana, where the drainages of the Missouri River watershed carve a complex network of coulees and creeks. The landscape is defined by the winding course of Rock Cr and Willow Cr in the east, while Lake Grable stands as a rare permanent water feature in the northwest corner. This area of Valley County exhibits the classic topography of the High Plains, where naming conventions for the terrain reflect early ranching and navigation. Family-named landmarks such as Harry Coulee, Riggin Coulee, and Starbuck Coulee provide essential geographic markers across the township lines of t36n r36e and t35n r37e. Essential travel routes through this sparsely populated territory are preserved via the Hinsdale N Rd and the Rock Creek Trl, tracing the path of least resistance through the rolling breaks.
