About this map

White Horse Creek and a network of intermittent waterways define this high plains landscape in eastern Garfield County. The drainage patterns of North Phillips Creek and Middle Phillips Creek suggest a seasonal rhythm of water management essential for ranching in this arid region. The presence of the Mincoff Ranch and the locality of Nelson represent the sparse but deliberate human settlement patterns typical of mid-century Montana rangeland.

Fine red dashed lines across the map indicate fence lines, marking out the vast grazing territories between features like Knudson Coulee and Red Horse Creek. This 1965 survey data, field-checked just as local infrastructure remained focused on the cattle economy, provides a detailed record of scattered wells and springs that sustained life in a territory where geographical landmarks often bear the names of livestock, such as Dry Little Creek.
