It's well worth a visit, read baza's fieldnotes - they're spot on in summing up the feeling of seeing the carvings close up. My favourite was a small bison-like figure that's just a couple of inches above you but really difficult to photograph, the bird is amazing too and a bit easier to capture. You find yourself staring at them in an open mouthed gurning chump kind of way.
Last time I was there was about a year and a half ago and the on-site sewage farm (I kid you not) was gone and the main road through the site had been dug up and replaced with a track, they've been spending a lot of money to try and get some kind of international status recognition I think.
