1991 Map of Unap Mountain

About this map

Unap Mountain and its massive central Quarry dominate this landscape of the Oklahoma plains in the early 1990s. The region is defined by distinct topographical rises and a network of drainages including Sugar Creek and Longhorn Creek. Near the community of Sedan, the terrain transitions from flat agricultural parcels into the more prominent elevations of Rainy Mountain and Longhorn Mountain. Local life and aviation history are evident at the Sugar Creek Ranch Landing Field in the southeast, while the Union Dale Church and Union Dale Cem serve as focal points for the rural community. Industrial activity is visible through a Gravel Pit and large-scale excavations on the slopes of the mountains, illustrating how the natural landforms have been utilized for resources while the surrounding plains remained dedicated to ranching and farming.
