SUMMARY: NASA's Spirit rover has dug up plenty of evidence on slopes of "Columbia Hills" that water once covered the area. Spirit has been inspecting an outcrop called "Clovis" on a hill about 9 metres (30 feet) above the Gusev Crater plains, and it's found that liquid water changed the composition of the rock. Unlike rocks in the plains, which have coatings and veins created by small amounts of water, these formations have been deeply affected by water over a long period of time.

I wonder where all the water went? Could it just have evaporated?

Sure, some evaporated, some sublimated from frozen surface ice, and some is still frozen on the Mars. How else could it have gone away?

Aliens! Just kidding :) That's really neat how they are finding out all this information from a couple of "short-lived" rovers. I can't wait to find out what else they find. It is very exciting.

Seems there is quite a lot, Mars is warmer than anticipated. Like an older Sister to us.
