It reaches a width of 29 kilometres at its widest point,and a depth of over 1.7 kilometres at its deepest. It formed as the entire plateau was uplifted,and the Colorado River cut into the underlying rock. The canyon was formed in the last few million years,but the oldest rocks in the formation date back over one billion years | |
