If you go to N33deg 53.76 min W93deg 53.7 min there is a huge hole in the ground.  This hole is located several miles north of Texarkana.  Is this a real place?  I'm guessing it is part of a canyon maybe??

(modified post) The cliffs in the hole look really impressive.  I took the bell down in and found a railroad bridge and electrical tower.  Flew out with a cannuck float plane.  Had to circle several times to get out but it was lots of fun.

Cool.  But I don't remember it being there when I was fishing the lake back in the mid 70's.
