Catastrophism Ping.
Several years ago Van Flandern and Hoagland put forth the hypothesis that Mars was hit by an exploding planet of which it was the secondary of the two-planet system. The asteroid belt is what remains of the larger body, and half of the crust of Mars including its atmosphere and most of its oceans were blown off in the explosion.
At a depth of 36 feet.
I know about the one "face," but I never heard about a second one.
Maybe a large asteroid that had the remarkable likeness of Kerry?

Number 432 (Story #3), June 7, 1999 by Phillip F. Schewe and Ben Stein
THE SURFACE OF MARS has been mapped to 13-meter precision, better than for some places on Earth. Laser light sent from and returning to the orbiting Mars Global Surveyor spacecraft reveals that the southern hemisphere is one big highland (6 km higher) compared to the northern hemisphere. Surface water, if there was any, would have collected in the North, although there is not yet definitive proof of any boreal ocean. One thing that is known about the northern lowland: it is the flattest place in the solar system. The South's elevation is due at least in part to an immense amount of material raised during an ancient impact which fashioned a huge crater known as the Hellas basin. (Science, 28 May 1999.)
Here's a Catastrophism ping list topic. This one shows up at the top, but is the last of the ones I've pinged you two to. :')
