> Dear Randy, I am a geophysicist and had a recent trip on Libyan desert for
> campaign of geophysical investigations, mostly GPR and Geoelectric
> tomography. Going back to the camp I found at sunset -due to low angle
> light- something strange on the flat desert surface.
>
> I found a perfect circular crater with melt sand scattered around . sand
> grains are melt and embedding larger quartz grains. In my opinion that's a
> impact crater and sand is melt because of the heat wave. Larger grains had
> no time to melt .
>
> That melt rock has a black matrix-nothing like that in the area, also
> there are no similar structures in that flat, flat flat desrt surface,
> sand is only silica and quartz grain and no dark matrix can be seen for
> kilometers.
>
> I made a few geophysics on the spot and found big electric anomalies and
> very anomalous readings of Geoelectric values.
>
> I took a few samples of melt rock -very heavy really.
>
> I am posting a few photos of the crater.
>
> I have another stone found at 2500 m on the bed of a melt glacier, same
> story, that's not a stone of the area, it is like a fuse, heavy and black
> inside with a very aerodynamic shape, I will mail you a photo ( after
> reading once more your recommendations) if interested . for sure not a
> human artifact or an original stone of the area.

> The round thing in the desert looks something like a crater. Maybe it's a
> bomb crater. Maybe it's a meteorite impact crater. The rock doesn't look
> like samples of Libyan desert glass that I've seen. I don't know the LDG
> story well. Has there ever been a crater associated with the glass?
