I have hiked this route (Overlook Trail) many times in Zion National Park.During July and August,huge summer storms roll in and can ...well,watch the video.Anyone caught down in the canyon hiking or Canyoneering will almost certainly die.There have been more then a few Deaths in Zion National Park from drowning and falls and rock falls.A quick Google search using "Canyoneering Deaths and Deaths at Zion NP" will show just how many. I have a cabin not far from here in Duck Creek Village and will retire here hopefully. One of the prettiest places in the world,in my opinion. Much more fun then the Grand Canyon as well. If you ever visit America, put this park on top of the list.
