The Drifts of Mars

Post by ET » Tue Nov 08, 2005 12:38 pm

I'm surprised that more hasn't been said about the rather obvious signs of long term pooling water in the basin of the crater (under the sand).

Am I mistaken?

The white outcrops contain a high concentration of salts which removes all doubt water play a roll in their formation. The data is still being analyzed to determine how long and how deep the water pooled. some location suggest the water wasn't ever more than a few inches deep while examining crater wall, some locations show evidence of water being present over millions of years but may have only been evaporation pools.
