1963 Map of Chalk Buttes

About this map

Chalk Buttes rises as a prominent landmark in this portion of Sioux County, defined by the expansive drainage of Sheep Creek. The landscape reflects the ranching operations of the mid-20th century, where water access dictated the pattern of settlement and land use across the high plains. A network of family-named windmills, including the Thompson Windmill and Grant Windmill, are scattered across the terrain, serving as critical infrastructure for livestock in an arid environment. Smaller holdings and homesteads like Nunzi Ranch and the Spurior Place suggest the persistent footprint of individual ranchers during this era. Surveyed as part of the Department of the Interior program for the development of the Missouri River Basin, the map also notes fine details such as the selected fence lines that demarcate property and range boundaries between Hatch Ranch and the surrounding open country.
