Grand Canyon Answers

Why did the Colorado River flow THROUGH the plateau instead of around it? How do potholes form on a 2,000-foot cliff, four miles from the river? How does a 5–10-ton rock get lifted into sedimentary rock? Why didn't the river spread out into the softer sedimentary rock when it hit the hard basement rock of the Inner Gorge? Enjoy learning the answers.
