There is a location in the French Alps that interests me. When I
view
it from satellite shots and from aerial shots it looks like it may
have been formed by a meteor strike. Unfortunately, I cannot find
this information anywhere. I am not a scientist, just very
interested. Is there someone here who could advise me?

I have a photographic link to the place but the satellite views
come
via Google Earth.

Hopefully, there is some source that keeps records of all known
impacts, but I have not been able to find it. Perhaps I am
completely
wrong about this place and it may have been formed by an ancient
volcano. But again, I find no mention of this anywhere.

Greatly appreciate your guidance.
Holly

Where? The French alps are not known for having volcanic features.
It is
mainly the result of thrusting.
There are some fine volcanic features in the pyrenées. Notably along
the
Spanish frontier on the Atlantic side.
I have not heard of impact features in the French Alps but then
again
I
have not studied that area very much.

If you don't mind, have a look at this aerial shot and tell me what
you think.

Satelite views also are interesting, but they are obtained through a
program like Google Earth and have no specific URL for linking to the
view.

Sorry that link does not work. Hope this one does.

Here are some links to the Geology of the French Alps. I hope this
helps:

Thank you George, for these. Perhaps I can gather something from the
last URL, but I'm not sure. Mont Aiguille is not part of Aiguille
Rouge. It is south-southwest from there in Vercors National Park. My
interest is specific to the area shown in the photo.
I'd like to determine if there were or were not a meteor impact there
or how that small cone like "island" in the center was formed.
Thanks,
Holly-

P.S. It appears to have central uplift as is typical of meteor impact
sites.


A quick check resulted in no results about impact
sites in France however I ran across a very interesting read from
http://www.geosociety.org/news/pr/06-47.htm

on newer theories of impacts and extinctions.

You might want to look at it.
