Hi from Argentina, This is about 60km(40mi) away from my home in Buenos Aires.<p>It looks like an interesting geological feature, but it's a pity that they mixed if with some UFO and paranormal bullshit.

All of them have almost the same text, so it look like they just copy-pasted the press release without any checking.<p>By the way, if you look carefully at the images, the outer circle is quite round, but the inner circle is like an oval.
