I only saw the final explosion. I was at the bottom of the grand canyon in complete darkness. I was sleeping on the beach at granite rapid and had just laid back down after being up when all of a sudden it was brighter than the day had been. Lasted about 1 second. One other person was awake in my group and saw it as well.
