You can see evidence of a transient brine water flow. I suspect it to be brackish h2o,
due to it's runoff from the adjacent mineral slopes.

Where's John Carter?

AT THE MOVIES!

Looking at the box office results and weeping.

Pity, I'd always been fascinated by John Carter, although I never got to read any of the books. I'd hoped the movie would do better!

Isaac Asimov's Science Fiction Magazine had a story done as a letter from John Carter to his nephew. He expresses confusion as to why the Mariner probes show a dead lifeless Mars whereas he's always traveled to a dying but still lively one. He realizes that he's been traveling back in the past when he goes to Mars and back to the present when he returns. He still doesn't understand why everyone's gone until he looks at a map of Mars and realizes that Mares Olympus, the huge volcano that probably resulted from a massive asteroid impact on Mars, landed right on their air reclamation facility!
