hmm , quite interesting - but the andes are fold mountains
IIRC charles darwin believed that the presence of marine fossils in striations hi on chilean sea cliffs was evidence of prior elevated sea levels .
later geolgy demonstrated that it was the mountains that had risen , not the seas fallen .
buut to get back to the point millions of years of geolgy has produced numerous anomolies .
here [ UK ] glaciation has left several granite and other igeneous rock bouders sitting forlorn in the midst of limestone landscapes .
the andes did not rise overnight [ geologically speaking ] , nor did they rise uniformly or consistantly .
so the news that the andes inevitably rose higer than the head waters of the amazon blocking its path to the pacific - and forcing the waters to flow
east - comes as no suprise
as someone pointed out - water flows down hill
still a bloddy intereting read though - kudos for bringing it to ATS attention .
