Here's that wet-spot on Mars that I mentioned:
Go to
http://artemis.simmons.edu/~sheinkor/project/pics.html
then click on "Mars Image Archive."
Then scroll down.
The picture, called "MPF_Jenkins_dune.jpg," CLEARLY shows a
muddy or damp water-hole of some sort, a puddle, a sump or
spring, something of the sort.--Mike
