High in middle.
I think it's this: At that kind of velocity, solids act like liquids. And you know how when you drop water into more water, there is a raised thing in the middle? Basically in the center the forces are all in and it goes up because it's moving in and on the outside things are moving out (and still a little down) and everything gets pushed out with them. And that's enough physics for me today.

Raindrops keep falling on my head
Have you ever seen a picture of a raindrop hitting a pool of water? For a split second as the drop hits there is a brief upward splash from the surface of the water just as a circular ripple starts to form Perhaps the suface was once very wet or muddy and it rained hard, I mean really hard!

How about elastic rebound? The theory: Whatever hit forced the surface layers of rock down, plasticizing them as well. They essentially BOUNCED back up, cooling the whole time, and solidified too much to drop back to level or below.

But Honey, I did put the seat up. Haven't you ever heard of elastic rebound?

If you zoom the Hubble cameras in real close on the wall of the crater you can see amazing detail!
