1973 Map of Glass Hill

About this map

The West Fork Poplar River meanders across this high plains borderland, where the Montana frontier meets the International Boundary in the early 1970s. This survey of the Maple Creek District in Valley County captures a landscape defined by seasonal watercourses like Mosquito Creek and Roanwood Creek that cut through the rolling breaks. Topographic landmarks like Round Butte and Glass Hill dominate the southern portion of the quadrangle, serving as essential reference points in a region of vast grazing lands. The human footprint here is sparse but deliberate, marked by scattered wells and agricultural storage bins, illustrating the late 20th-century reliance on managed water and grain storage in the remote northeast of the state. Settlers and ranchers in the area navigated a terrain etched by the broad depression of Happy Valley as it parallels the river's winding course.
