1972 Map of Mount Helen

About this map

The Old Indian Treaty Boundary carves a significant historical line through this high plains landscape at the border of Kansas and Oklahoma. This 1970s survey captures a region defined by its hydrology and mineral extraction, where the prominent height of Mount Helen overlooks a network of watercourses including Fivemile Creek, Twomile Creek, and Sandy Creek. The terrain is marked by the presence of industrial infrastructure, specifically a Pipeline and numerous scattered sites labeled Gas Well, alongside a Caliche Pit and a notable Drill Hole. These features illustrate the mid-century transition of the southern Great Plains as traditional ranching and land boundaries integrated with modern energy development. Natural water sources like Springs and a man-made Reservoir further emphasize the critical nature of water management in this arid transition zone between Clark and Meade counties.
