[Geology2] Ancient 'wrong way' river discovered

Ancient 'wrong way' river discovered
United Press International, Oct. 5, 2010

Geologists say a river as big as the modern Colorado flowed 55 million
years ago in Arizona and Utah -- in the opposite direction from the
present-day river. Researchers in the Department of Global Ecology at
the Carnegie Institution in Palo Alto, Calif., have named this ancient
northeast-flowing river the California River, after its presumed source
in the Mojave region of Southern California, an institution release said
Monday. By analyzing sand grains in sedimentary deposits in Utah and
southwest Arizona the researchers were able to determine that the sand
at both localities came from the same source -- igneous bedrock in the
Mojave. The river emptied into a large lake in Utah more than 400 miles
away from the California source, scientists say.
