Well there's the frog perched on the right. A turtle head left of center, and what looks to be Nixon on the left. Those are most prominent. Great shot.
I love things like this! I found 21 faces (some unearthly) counting the sky and vegetation as well as the rocks...and that was just when I quit because I absolutely have to get something done this evening. I downloaded 2 copies of your pic (one small) and marked what I saw so I could keep count. I'll send the marked copy to you if you like...:)
