Hi, Anne,
Knowing that the crater field in SW Egypt has already
been "discovered," I didn't examine it. The first crater I
listed is 35 miles inside Libya. Kebira itself lies right on
the Egypt-Libya border, with about 60% of the crater lying
in Libya. Whoever goes to poke and probe it will need
the cooperation of TWO governments... Bon chance.
The second candidate I listed is in Chad and is possibly
reachable from the Aozou Airport, assuming you could ever
get permission to fly in. Again, bon chance.
The craters shown in the article are at such a small scale
(1200 meters and down) that the search in, say, GoogleEarth,
would be arduous. They're great little craters, though, and
are pretty unmistakable when seen at ground level. And
the shattercone photo is one of the best photos
of shattercones in place that I've ever seen.

Hi, Darren, List
I've been searching the desert for additional craters, too.
Here's a couple more candidates beside the two mentioned
on the astroseti.org website.
Let me stress that I am neither a geologist nor an aerial
photointerpreter, so these are just what looks good to me.
First, 37 miles WSW of the newly noticed Kebira crater,
at 24 deg 34' North and 24 deg 24' East, is a 2.57 mile
crater. It has no central uplift and has been cut by ancient
stream courses, so that its interior is at the same level as
the surrounding terrain. The rim is raised 100 to 300 feet.
There are fairly clear traces of an outer ring with a diameter
of approximately 9 miles. The ancient eroded outcrops in
which it lies all have features that run a little west (east)
of north (south). The crater's arcuate features cut right
across the "lie of the land."
Frankly, it looks as much (or more) like a crater than
Kebira itself. The imagery I can access is not detailed
enough to examine the rim for upturned strata.
Secondly, at 22 deg North and 16.5 deg East, there are
a number of features that are eliptical in nature stretching
to the west of the indicated location. This is a region in which
old outcrops running almost north-south are being "submerged"
in the Great Sand Sea. Many features are irregular ovals filled
with sand to the same level as the surrounding terrain, are
probably former ancient lakes, and lie at the margins of the
outcrops, as you would expect lakes to do. <SNIP>

For more information on that area, did you look on my website at the
report
published by a French Expedition: http://www.impactika.com/acarion.html
And the article in the August issue of Meteorite magazine, written by
Alain
Carion.
They have already found upward of 100 impact craters in that area. Some
are
clearly visible on the pictures.
Enjoy!
