This was shot literally 10 mins before it got dark. Whats crazy is that you really need to walk up to the edge of the precipice to be able to look down (into a 300+m drop to the Colorado River!) and get a good view. Pretty wild!

 

Here's a different view shot a little earlier that day: www.flickr.com/photos/rajuvaidyazuiq/7858583664/in/set-72...
