Re: African falls
Dear Jeff,
They seem plenty different to me.
(I hope your comment about their having been witnessed falls in NE
Africa is not as racist as it sounds. "Vaguely?")
Hamada du Draa fell in January & El Hammami in August.
A friend of mine packed El Hammami out of the El Hammami Mountain range
on cammels. I can't vouch for Hamada Du Draa, but my impression is it is
at least several hundreds of miles removed - but even if it is only a
hundred, in that part of the world, a hundred miles is a very long way.
The El Hammami I have looks PERFECTLY freash - the Hamada du Draa looks
slightly weathered, and they have differences in appearance of their
matrix in general.
