1972 Map of Bonnie Reservoir

About this map

Bonnie Reservoir and the surrounding rangelands along the Campbell and Crook county line are detailed in this early 1970s survey. The landscape is defined by a dendritic drainage pattern where the North Fork Little Missouri River meets various seasonal draws and prongs, such as Mitten Prong and McKim Draw. Ranching life is evident through the inclusion of the Horse Creek Arena and several small water management features like Wenande Reservoir No 1. Physical landmarks like Monument Hill provide topographical orientation in an area largely characterized by these vital water sources. The map also traces modern infrastructure of the era, including a prominent Pipeline and scattered Drill Hole locations, indicating the integration of industrial resource extraction into the traditional Wyoming high plains grazing environment.
