Lake Kivu far to the south was in the Nile drainage basin as recently
as 17,000 years age. There is a series of basins which are known to
exist nearly to the mountains which rose up to cut off Lake Kivu. This
lake itself is one of only three carbonated lakes in the world.

If there were a basin on the north side of this mountain chain it too
could have been carbonated and would still supply CO2 to Giza for 600
years after it was tipped to the north and emptied. This event may have
lasted from 15000 BC until shortly after the Giza pyramids were built.

Cold water geysers are similar to the better known hot water geysers in
that they are propelled by the top of the underground water flying up
reducing pressure on the deeper water which causes it to fly as well.
In hot water (thermal) geysers this is caused by the water boiling. In
cold water geysers it's caused by the water fizzing up. Cold water gey-
sers can actually throw more water to greater heights and much more con-
tinuously than the thermal geysers. Most cold water geysers today are
man made and this was probably true in ancient Egypt as well.
