1979 Map of Harper Coulee

About this map

Harper Coulee carves through the central terrain of Musselshell County, defining a landscape marked by essential water sources and specialized land use in the late 1970s. The presence of Thompsons Water Hole and Hay Spr underscores the critical importance of reliable water access in this semi-arid region, likely supporting local livestock and ranching operations. To the north, Halfbreed Creek and Goulding Creek drain the higher elevations, while a Drill Hole and several wells suggest subsurface exploration and resource management. The map reveals a network of primitive roads and fence lines that segment the land, reflecting a period when range management and scattered hydrological points were the primary drivers of human activity across these coulees.
