re: Mars: Freeze-dried (Surface) for over 3.5 billion years

It would seem Mars' surface has been "freeze-dried" for billions of years and yet there are problems with this assessment.

There are signs that some surface areas on Mars have been active in real recent geological times...like months ago...

And you find stream beds, meanders and oxbows with little evidence of impacts and filling and others nearly obliterated...what does this tell you? That is to say if we can date these river and streams to a time after the Noachian Period what then?
