Assuming the lights to be from a car, Barton drove toward them in order to intercept any unauthorised trespassers. The lights vanished when he arrived at the site where he had last seen them, but now he found his vehicle mired in the soft desert sand. Walking approximately two miles back to base, the sergeant intercepted a patrol and they radioed for a tow truck. When the truck arrived and everyone returned to the Sergeant’s vehicle, they found 3-toed tracks measuring 14 inches long with what appeared to be a clawed digit at the heel. The wind was blowing soft sand and the footprints were filling in rapidly, making any precise identifications difficult. But whatever “it” was that left the tracks had completely circled the truck as if inspecting it and then walked off on two legs into the desert.
