Being an ignorant American, I had never heard of Pic de Bugarach before, but evidently it's well known in Europe as a center of woo (kind of like Mount Shasta or Sedona here in the States). Just Google Pic de Bugarach and you'll see all kinds of references to UFOs, aliens, ley lines, vortexes, and ancient treasures of the Templars.
What really caught my eye, however, since I'm a geologist, was the following:
Pic de Bugarach has long been famous because rock samples taken from its peak are actually older than points measured at lower elevation. Scientists say that is because when the 1,230 meter mountain erupted its peak flipped upside down before crashing back down upon the mountain's base.
What dumb ass "scientists" say this?
The CNN video link in the story calls the mountain a "scientific anomaly" as if it's completely mysterious.
Even though I'm completely unfamiliar with the geology of Pic de Bugarach, I do know that mountains don't erupt and flip upside down. Especially one that looks like it's made of limestone and has caves (that's where the aliens hide).
Let's ignore the clumsy prose of the author of the Yahoo! News article and ask "How come rocks collected from the peak of Pic de Bugarach are older than than rocks collected at the base?" Well, to a geologist, that would be a classic indicator of a thrust fault - a place where horizontal compression of the crust, during mountain building, thrust a sheet of rock up and over younger strata. Happens all the time and is seen in mountain belts (modern and ancient) all over the world (even, on a small scale, here in the Hudson Valley).
Thrust fault emplacing older strata on top of younger strata
So, I did some "research" (a Google search) and quickly learned that I was, in fact, correct. Pic de Bugarach is a klippe - the erosional remnant of a thrust nappe formed when the Alpine Orogeny formed the Pyrenees. Jurassic limestones are thrust over younger Cretaceous rocks in the area.

This is very similar to a place I am a bit more familiar with, Chief Mountain in Montana. Chief Mountain is also the erosional remnant (klippe) of a thrust sheet.
Anyway, it's pretty cool geology but it's not particularly mysterious. Pictures and descriptions of these features are seen in every single undergraduate textbook which discuss geologic structures and tectonics.
So, just because you read it in a "news" article, doesn't mean it's true, boys and girls. Mountains don't just leap in the air and flip over. And aliens don't live in caves under a mountain in France.
