This place had the most dynamic display of light I have ever seen. One could actually physically see the light move across the sand as these beams grew and faded. The best part about that was that our guide knew exactly when and where each of these beams would appear. For one of them, he told our group of photographers to stay right where we were and not to let anyone take our spot as more and more tour groups poured through the canyon. He pointed to a spot in the sand and said, "It's going to start right here in 3 minutes." He was spot on!
