Any geologists out there? What is that thing?

Yesterday, we drove to Gillette, Wyo. to help celebrate my wife's aunt's 90th birthday. On the way home as we went by Sundance mountain, I started wondering how all of that looked from the top... you know, Devils Tower, Sundance Mountain... the whole area. So this morning I was looking at Sundance on Google Earth and noticed this almost perfectly circular formation just east and a little north of the Sundance mountain. (Upper right in this screen shot.) Anybody know anything about it? Does it have a name? Is it an "intrusion," a volcano? A really, really big fossilized buffalo chip? Or what?
