Nope, newberry is just a little bit north of it though. Thats Crater Lake to SW.

It's not on the list of known impact sites. If I remember right when I measured it using the google earth tool it's about 27 miles across. Next time I'm over that way I'm going to ask around.

old wise tale is that a very large volcano occurred in that area a looong time ago.  a mountain as big as everest blew its top.  when i was told the size of the mountain i was shocked.  It was something like the area of north klamath county.

Well...Crater Lake (Mt Mazama) blew it's top.  Something like 10 or 11 thousand years ago.  And there is an ancient caldera, a couple million or so years old, in south eastern Oregon, that was caused by the hot spot that's under Yellowstone now. This is neither of those.  If you look at ancient super volcano calderas, they look nothing like this.  If you look at  known impact sites, they look a lot like this.  I'm not saying it is an impact site. Maybe vegetation on the ground in this photo is giving it the round shape. Although the feature on the NW side is called something or other Rim. ( I can't remember the name right now) I did look around on the internet and such and found no reference about this thing. I can't believe no one has noticed it before.

Looks like multiple impact craters side to side (and smaller impact craters). Something caused the circular growth of the vegetation, and circular
depression next to it. Bet that body of water SW is also a small one.

Well I did some more research and both circular areas and much of  the SE quarter of the state are included in what is called the Rift Volcanoes. (12 to 2 million years ago) These volcanoes, some 790 of them, are apparently linked to the Yellowstone  Hotspot.  According to the couple of paragraphs I could find they are a result of the aftermath of the hotspot. Even though it traveled through the very SE tip of the state. (or more correctly the state traveled across it) The hotspot is also blamed for some giant basaltic eruptions in the Columbia river basin way up north.

Still looks like an impact to me.

Oh well I'm no geologist.

Sorry about the hijack.  

 :cheers:

p.s. Oz, that is Crater Lake Nat'l Park.  A volcano that blew its top, then filled with water. Absolutely awesome place!
