A Friday Mystery Photo from Kings Canyon National Park

No, I don't have endless supplies of mystery photos, but there are still a few in the files. This one is from our recent meeting of the Far Western Section of the National Association of Geoscience Teachers. We were at Road's End in the South Fork of the Kings Canyon looking at glacial moraines, when several of the group noticed the odd outcrop on the cliff above.
The rock is probably granodiorite (Lookout Peak or Paradise Pluton), and there are glacial moraines on the valley floor below. So what is going on here? Why the linear patterns on the rock face? Why the pockmarks? What do you think?
Oh, and there's a small secret in the comments...
