At around 17 million years ago, while the river was flowing across this ancient landscape, the land mass know as todays Colorado Plateau began to uplift. The uplift was caused by pressures deep with the Earth and may have been caused by additional conflict between the North American Plates and the Pacific Plates. This process continued until around 5 million years ago which interestingly enough is the date of the sedimentary layers just west of the plateau. At its greatest hieght the Colorado Plateau was once about three miles above sea level. The rise of the plateau probably prevented the seas from submerging it again and instead the topmost layers were eroded away and carried into the sea. The most favorable currently accepted theory is that the Colorado River continued to cut through the Colorado Plateau while the land rose around it.
At some point around 5 million years ago something happened to cause the Colorado to change its course and exit via its present route down to the Gulf of California. The most likely cause for the change in its course was probably due to it being captured by another river, which was draining the western portion of the Colorado Plateau. This other river eroded northward along the San Andreas fault, then eastward and eventually entered the Grand Canyon and joined with the Colorado near present day Kanab Creek. The Colorado would then have abruptly changed its course and flowed out this newly formed exit.
