About this map

Round Butte serves as a prominent natural landmark in this high plains landscape during the late 1970s, anchoring a region defined by its sprawling drainages and ranching terrain. The map traces the boundary between Chouteau Co and Judith Basin Co, capturing a transition where the Libby Hills give way to the broad expanse of Jiggs Flat. Water is the primary sculptor of the land here, with Cottonwood Creek and Cowboy Creek cutting through the territory.

Evidence of early frontier presence is found at the settlement of Gerard and a solitary Grave located northeast of the butte. The intricate network of intermittent streams, including Fall Creek, Davis Creek, and Ole Coulee, illustrates a seasonal hydrology typical of central Montana. This survey provides genealogists and land researchers a clear view of the rural homesteading patterns and the geographical relationship between named family landmarks and the rugged coulees before modern development.
