Obi-Wan enters the clearing pursued by a Federation STAP. Qui-Gon destroys it, and parts of the wreckage tumble into a hollow to the right of the clearing.

Another montage from the film (with motion blur) showing the path of the STAP wreckage.

The hollow is real, as shown above. The wreckage flies past the tree on the left and rolls down the slope past the bush in the background.
