1972 Map of Arpan Butte

About this map

Arpan Butte dominates the southern landscape of this 1970s topographic survey, marking a distinct terrain feature in a region defined by an intricate network of drainage channels. The area exhibits a classic Western watershed pattern where numerous ephemeral draws, such as Redman Draw, Long Draw, and Fowler Draw, feed into larger systems like Thompson Creek. Human modification of this arid environment is evident at the Bill Yates Reservoir, a critical water management point located near East Fork Thompson Creek. The map also delineates the boundary between Sheridan Co and Johnson Co, providing a clear record of administrative borders as they intersected the natural topography during the early 1970s. This survey is particularly useful for understanding local hydrology and land use before later twentieth-century developments.
