Re: 13,000 years ago
- Stan, Oz. and All,
Fantastic article, Stan. Great things coming in from groups of
geologists and geophysicists the past few years and I hope to hear
more as evidence and joint research continues. 12,500-13,000 years
ago (and earlier) are time periods I am most interested.
Several months ago I had sent an article to this group and to the
Great Pyramid of Giza Research Association on the 'Grand Canyon of
the Nile' beneath Cairo, and the 5th, or present-day course of the
Nile River appears to have begun around 12, 5000 years ago. This
would fit nicely into the theory of the comet and resulting
cataclysmic climactic/earth/waterway changes:
"....The Modern Nile began flowing 12,500 years ago (Holocene). The
article summarizes: "A vast deep canyon, which five million years ago
looked like the Grand Canyon of Arizona, lies buried under Cairo, and
extends southward for 600 miles to Aswan, Egypt, where its further
path is lost."
Source: "Vast 'Grand Canyon' Lurks 8,200 Feet BENEATH Cairo, Egypt":
Thanks for the updates on the radio programs, Oz. I work late
Thursday nights, have missed the last three arctived programs because
of computer problems. Double-shifting a lot lately, my PC seems to
have a 'bug', and very difficult to get on-line as before.
