Hi Listers - This message of Bills and others that he sent came in with a notebook type of attachment which is a duplicate of the message it accompanied.

Did anyone else receive messages that way? and would anyone know why? Joyce Crete

'Dancing elephants' help chart prehistoric Canada
06 Oct 2004

MONTREAL - Imagine an ocean on the Prairies and mountains higher than the
Himalayas in Ontario.
That's part of the picture unveiled by Lithoprobe, a 20-year examination of
Canada's ancient geological history. Named for the probe of the lithosphere
(the earth's outer shell) the project used 20,000-kilogram trucks dubbed
"dancing elephants" to generate some of its data.

Since 1984, more than 800 university, government and industry scientists have
been examining the movements of ancient continents, oceans and islands,
piercing together the evidence to draw a map of Canada's origins.
They call it "Canada's basement," a view of the country 80 kilometres deep
and 6,000 wide.
"Underneath the surface of Alberta, we found a subsurface mountain range,"
said Dr. Ron Clowes, Lithoprobe's head and a professor of earth and ocean
sciences at the University of British Columbia.
Even more spectacular, "There was once an ocean ... on the scale of the
current Pacific" under modern day Saskatchewan and Manitoba.
Often working in groups of four, the dancing elephants – more properly called
vibroseis trucks – created seismic waves by co-ordinated bouncing on a pad.
The waves are reflected back from the earth, but the reflections vary,
depending on what the waves hit.
The reflected waves are then recorded, producing data and charts.
The information is already being used by mining companies to explore for
minerals, and is providing data on the process that might lead the volcano in
Mount St. Helens, Wash., to erupt.
