Thanks FieryIce. and Norval.
I came across this picture the other day and it had me thinking. I still think I am on the right track.

Craterchains may find this interesting too if he has not seen it already.
The marks I see on the surface may or may not be debris marks from acretion debris taken in the process described in the original posting, but the marks have a distinct orientation and a fairly acute strike angle which would line up with some debris falling back in the process. Perhaps they are not strike marks at all but they provoke thought in a similar direction.
What would be interesting would be to go down to the altitude they may have come in at and look at the strike patterns again which with the topography of the surface- may produce a more linear pattern.
Regards a thought process-- Lets say Mars did have the water and an associated atmosphere to go with it to retain the warmth and the liquid state. Lets say the atmosphere and the water were taken -- (preferably by my original process.) Now consider recent meteor encounters with Earth that come in at a shallow angle to Earth and begin to burn as they hit the atmosphere and then bounce off again. What I am saying is- the acute angle will bounce objects away again and if they dont bounce off they are slowed down to strike with a fairly vertical angle.
Lets say that with mars-- after the event- the water and most importantly the atmosphere went with it, we would see some recent crater evidence of meteor strikes with fairly acute strikes compared with older - atmosphere strikes.
To sum up-- I am trying to say (badly) a study of old water and atmosphere present strikes compared with new atmosphere and water gone strikes may show a more acute strike angle for the latter. It will take a while with my steam driven computer at 24000 bps- an hour for one picture the other day. Dial up and bad country lines!
I am still thinking about the Texas Tea.
