1984 Map of Antelope Pass

About this map

Antelope Pass anchors this high-elevation landscape in Valley County, where the topography is defined by a complex drainage network of creeks and coulees. Surveyed for this 1984 provisional edition, the area demonstrates the intricate watershed of Rock Creek and Deep Creek, which snake through the terrain alongside family-named landmarks like Starbuck Coulee and Jones Coulee. The mapping of Upper Lake and the nearby Ichpair Creek suggests a remote, sparsely settled region where land use was likely tied to seasonal water access and livestock grazing. This survey provides a precise record of the natural contours and seasonal waterways, such as Dry Coulee and Marsh, before more modern alterations to the Montana backcountry.
