1985 Map of Hydro

The northeastern portion of the map transitions into the American Horse Lake State Hunting and Fishing Area, highlighting the region's managed natural spaces. Drainage patterns are dominated by the Deer Creek system and the deep cuts of Cedar Canyon, illustrating the erosive character of the local geography. Significant landmarks such as the Groendyke Ranch Airfield and the curiously named Dead Woman terrain feature provide specific points of interest for those studying the Caddo and Blaine County borderlands.
