1956 Map of Unap Mountain

About this map

The Rainy Mountain Indian School Reservation occupies a significant portion of this Kiowa County landscape, marking a central point of institutional history in the mid-1950s. The terrain is defined by prominent elevations including Rainy Mountain, Unap Mountain, and Longhorn Mountain, which rise above the surrounding plains. The small community of Sedan sits in the northeast corner, while the Union Dale Cemetery serves as a localized genealogical landmark in the southwest. This map records the drainage patterns of the area, notably Rainy Mountain Creek, Longhorn Creek, and Sugar Creek, illustrating how these watercourses navigate the township boundaries of Harrison, Mountain View, Cooper, and Marshall. The survey captures the rural character of the region just as photogrammetric mapping was refining the precision of Oklahoma's topographic records.
