On August 10 of this year, a large storm cell dumped significant moisture on the south facing Vermilion Cliffs near the small settlement of Cliff Dwellers. A passing motorist shot this video which shows huge rooster-tail waves running over the highway. A local news report had this to say about the large runoff event.
On August 22 I was at the site of the flood, preparing for an 8-day river trip in Grand Canyon. I drove to the culvert area for this unnamed wash and shot pictures of the debris that was still present near the roadway.
