This is in response to R’ Bamberger’s Shmuez 2 fridays ago.
I don’t know if this is the “real deal,” but the rock does look like a face, with a nose, etc. (source: http://www.flickr.com/photos/lelgustur/3708158256/) 
As a side note, I think that the “Baal Peor” of us today is in dealing with terrorists in Israel. What we normally do to scare people off is to kill them. What do we do with a culture that welcomes death? This is the exact opposite reaction we would expect, similar to worshipping Baal Peor being the exact opposite of what one would expect.
A funny story about Baal Peor can be seen on my blog, as a side note to “R’ Zusia and the waste pail.” https://www.mywesternwall.net/2010/04/02/rabbi-zusia-and-the-waste-pail.html
