About this map

Chalk Buttes anchor the southern landscape of this eastern Montana survey, where the rugged elevation transitions into the broad expanse of Beaver Flats. This cattle-country terrain in Carter County is defined by its vital water sources, including family-named landmarks like North Harkins Well and South Harkins Well, alongside several natural flows such as Ewalt Creek and Little Beaver Creek. The presence of Bronco Sam Spring and Michael Spring within the Custer National Forest boundary reflects the critical role of reliable water in this semi-arid ranching region.

Infrastructure is sparse but significant, centered on the Powderville Road and a localized network of unimproved tracks. Prominent topographic markers like Newberry Knob, Newberry Hill, and Big Hill—the latter topped with a Radio Tower—served as essential navigational waypoints for locals. The map also identifies industrial traces such as a Gravel Pit and scattered wells, providing a detailed record of the land use and natural resources during the late 1970s.
