Re: Lunar Impact crater ages
<<Could it be that the cratering we see happened over a relatively short period of time?>
Actually the cratering on the Moon happened over a very long period of time. Craters impacts on top of other crater impacts with fresh ejectile material scattered over the surface is one clue such as Tyco. Craters are classified according to there age, Class 1 being the youngest and up to Class 5 thought to be formed near the time the Moon was formed.
