See the white stuff? that's snow on the Kaibab Upwarp. How could water erosion cut through the change in elevation at right angles to the slope? There would be 1300 cubic kilometers of debris at the mouth of the Colorado

Not saying it's likely to happen anywhere tomorrow of course, but the North hemisphere of Mars was eroded 6 miles deep and the material was deposited in the Southern hemisphere.

Awesome, freebeard!
