I'd call it: The Druid Tree

Tree carving

I love trees, and when I came across this one while trail-riding in Wyoming I had to stare at it for a while before snapping the photo.

This particular ranch had a number of trees carved with ancient faces.  Though it was mid-day, it was always a bit eerie to round a bend only to be greeted by a druid-face, carved in relief and six feet in height.

Our guide suggested the carvings don't hurt the trees, but I don't know.  The trees looked a bit sorry to me!
