I don't have the picture on my phone however I went hiking in California a few years back and for those that don't know there basically a huge rock called half dome...

You can climb the top of this via this very very steep 'Ladder'

And then once at the top there a disgustingly exposed rock hanging over the edge, knick named 'the diving board', which is as much information you need to put you off haha.
This is just a Google image but it gives you an idea of the selfie I have somewhere....
