Perfect for astronomy/astrophotography. Not a very well-known site for these persuits, but it's only 45 minutes from hotels in Elk City and Shamrock. Very well-maintained place with good facilities (tables, parking, etc) and not too far from civilization if you get into trouble or need emergency services. Attached is an unprocessed image of Andromeda, 10-second exposure through a telescope running at f/7.5 and no LPR filter. Highly recommend if you're passing through Oklahoma on I-40 and want to see actual dark skies relatively free of light pollution.
