Albert Pike Recreation Area

It seems the Albert Pike recreation area was the most affected are in the camping park, where hundreds of people were camping when this flash flood surprised them.

During the course of the night, waters rose 20 feet after heavy rain concentrated in the region.  People were sleeping when the waters devastated the areas, turning RVs and carrying away tents
