2017 Map of Dudley Spring

About this map

Dudley Spring and the expansive drainage systems of the Montana high country define this portion of the border between Big Horn and Treasure counties. The landscape is characterized by deeply incised seasonal watercourses, including the evocatively named Fountain of Youth Coulee and Horse Pasture Coulee. Settlement patterns in this ranching environment are scattered, with topographical features like Poverty Flats and Sawmill Draw suggesting the historic land use and agricultural challenges of the region. The map reveals the intricate network of the N Fork Pocket Creek and S Fork Cottonwood Creek, illustrating how water sources dictate the geography of this arid northern plain. Researchers can trace the complex system of coulees such as Rough Springs Coulee and Smith Coulee that branch across the townships, providing a clear picture of the natural boundaries that shaped local grazing and land claims.
