1982 Map of Pentecost Reservoir

About this map

Haystack Butte and the winding drainages of the Powder River Co Carter Co line dominate this 1982 topographic survey of southeastern Montana. The landscape is defined by an intricate network of intermittent waterways, including the three-pronged system of Dry Creek, North Fork Dry Creek, and South Fork Dry Creek. Human infrastructure is sparse, characterized by a few Landing Strips and several Drill Hole markers scattered among the draws. The namesake Pentecost Reservoir and its associated Pentecost Draw serve as focal points in the southern portion of the map, illustrating the essential role of water management in this arid ranching country. From Reynolds Draw to the deeply etched Kuster Canyon, the topography reveals a highly eroded terrain where every named feature relates to the flow of water or the distinctive rise of buttes.
