The canyon is vast, the height of the cliffs vary greatly from one end to the other. Maximum depth is about 6,000 feet.
I was just there and I was told that 1 mile deep is a good estimation of the average depth from top to floor
1000~2000 meters. You can't imagine how deep it is before you see.
The canyon is chulisimo to see it but there you go through a guide you stay in Arizona and when they make the expedition you sign up and they take you they give you chocolates to put up with that heat and water vitamins so as not to faint.
