OK, I should have known better. Here's the link to the picture I tried to post...

WOW!! Now THAT's inspiring! Thanks!

BTW: Do you know about the geology of this region? i.e. are those rock formations that the water is flowing over ancient lava flows?

I don't know much, but I found a Web site that does:
