From Black Canyon City, Arizona, at about 2000 feet elevation, we went to the Grand Canyon National Park, which is at 7000 feet elevation. The drive was a 3 hour uphill climb. The area is at a high elevation because of the uplifting of the Colorado Plateau. Approximately 5 million years ago the entire Rocky Mountains and Colorado Plateau were uplifted 4,000 to 6,000 feet.
