About this map

Sevenmile Ranch anchors this high plains landscape in Lincoln County, where the hydrology of the eastern Colorado steppe is meticulously documented. The map details the headwaters and drainage patterns of the South Fork Republican River, fed by several ephemeral watercourses including Buffalo Creek, Sevenmile Creek, and Coon Creek. These drainages define the rolling topography and historical ranching boundaries of the region.

Interspersed among the draws and ridges are vital infrastructure points for arid-land ranching, such as various locations marked Well and a central Tank. The inclusion of a long-distance Pipeline and a local Gravel Pit indicates the industrial utility of the land during the late 1970s. For the local historian, the map preserves the exact placement of fence lines and water sources that sustained rural operations in this part of the Republican River basin.
