floating rock like object, seen by two security officers the size of a mini-van.The object was a little bit bigger then a car, it was noticed around 1600 or so. the object was first seen floating in the air, it just sat there. the object could have passed for a rock if it were sitting on the ground, it looked like the same texture, and material of a rock. it was a brownish color. it hovered about 25 to 30 feet off of the ground, and just sat in one spot for several hours. after 2 or 3 hours of it sitting in one spot, it changed directions and flew off, and right before it got dark you can see it in the photographs trying to return to where it had originally been before we noticed it.((NUFORC Note: Witness indicates that the date of the sighting is approximate.
