1984 Map of Ryan Butte

USGS Topo · Published 1984

About this map

Ryan Butte rises above the drainage networks of Chouteau County in this mid-1980s landscape, characterized by the intricate headwaters and coulees of the Missouri River basin. The terrain is defined by prominent topographical markers such as Flying A Butte and Mc Namara Butte, which likely served as critical orientation points for early ranching and surveying in this portion of Montana. The map documents a complex system of seasonal and perennial waterways, including the winding course of Eagle Creek and its tributary, Little Eagle Creek. These drainages, alongside Little Sandy Creek and Godfrey Creek, illustrate the natural erosion patterns and land use boundaries of the region. The inclusion of Salt Coulee and Dog Creek further highlights the hydraulic character of the plains, where small elevation changes and water access historically dictated the location of homesteads and grazing lands.
