Sierras higher in Late Cretaceous

["Cunningham, Betty" <bcunning@nssi.com>]

        In the new issue of Science magazine there is an article about the 
     Californian Sierra Nevadas and how they were likely to have been as 
     high as the Andes-up to 13,000 feet- 70 million years ago. (They are 
     currently about 9,000 to 10,000 feet)
        This is a change from the more common view that they only started 
     to rise about 10 million years ago.
        No wonder we have so few dinosaur fossils...they've been washed out 
     to sea millions of years ago.
