|This observation platform juts out over a deep round sinkhole with sheer rock walls over 100 feet tall. This is on the downstream side of the park.
The crew is using a videocamera mounted on a crane to get sweeping shots of the sinkhole and cave far below. From left, Denise Vaughn, Neil Rosenbaum, and Kevin Kaiser.
Shot of the cave mouth taken from inside the sinkhole. The photographer is standing not far from the bottom.
