As is the case in many National Parks, and even out and about on local roads and scenic overlooks, you must be VERY CAREFUL where you step, and how close to the edge you get.
After walking out to one of the viewpoints I walked back up the steps towards the Lodge and saw this tree, which I thought made an interesting picture.
I took one photo, then another from a little further back.
I still wanted to get further away and looked behind me before I took yet another step back. Good thing I did. This is the ledge I would have dropped off of.
And would then have fallen down this embankment.
You have GOT TO pay attention to your surroundings at all times. Many people have literally fallen to their deaths, or suffered severe injuries, trying to take that perfect selfie.
