Claim CD210:

There is nowhere near enough sediment deposited at the mouth of the Colorado River to account for ten million years worth of erosion.


  1. The Colorado River delta itself is quite extensive. It covers 3,325 square miles (Sykes 1937) and is up to 3.5 miles deep (Jennings and Thompson 1986), containing over 10,000 cubic miles of the Colorado River's sediments from the last two to three million years. The sediments that were deposited by the river more than two to three million years ago have been shifted northwestward by movement along the San Andreas and related faults (Winker and Kidwell 1986). Sediments have also accumulated elsewhere. Some were deposited in flood plains between the delta and the Grand Canyon.

  2. Wind is a major erosional force in parts of the Colorado River basin. Some sediments from Colorado and Wyoming were blown as far as the Atlantic Ocean.

  3. Much of the strata exposed in the Grand Canyon are limestone and dolomite. These rocks eventually simply would have dissolved.
