1984 Map of Arrowhead Reservoir

About this map

Pine Ridge dominates this Wyoming landscape, where the high plains transition through a series of named draws and canyons. The map records a complex drainage system defined by Little Piney Creek, Arch Creek, and the headwaters of the Green River. Water management in this semi-arid environment is evidenced by features like Hagerman Reservoir and the CB&Q Reservoir, the latter suggesting a historical link to the Chicago, Burlington and Quincy Railroad. The county line between Crook and Weston Counties bisects the terrain, showing how political boundaries were surveyed across these high-elevation ridges. Small-scale industrial activity appears at the Clay Pit, while the numerous named landmarks like Wolfe Draw and Philpott Canyon reflect the localized geography used by generations of ranchers and land managers in the Black Hills region.
