Dear Friends,

A paper about a proposed Pleistocene impact in the
western Desert of Egypt is in press in the Earth and
Planetary Science Letters.

It is:

Osinski, G. R., H. P. Schwarcz, J. R. Smith, M. R.
Kleindienst, A. F.C. Haldemann and C. S. Churcher.
in Press, Evidence for a 200-100 ka meteorite impact
in the Western Desert of Egypt. Earth and Planetary
Science Letters. available online December 2006

This paper argues that unusual silicate glasses found
near the Dakhleh Oasis, Western Desert, Egypt is the
result of either a "cratering event or a large aerial burst",
which occurred about 100,000 to 200,000 year ago
according to Ar/Ar dating and geoarcaheological
