I just watched a show about the Grand Canyon. For the River to have dug out the entire canyon, a sediment layer of unimaginable proportions should exist at the rivers outflow. Have there been any significant geological excavations here to;
1. Analyze the rock types deposited for comparison to the Grand Canyon and,
2. Look for Fossils that have been washed out here.
3. Look for evidence of the 30 MY gap in the ageing of the formation "stack" at the Grand Canyon.

Thank you
