A River Once Ran Through It

Mars once was wet but is now is dry---super dry. Evidence for an extensive river system was recently announced by the European Space Agency when they published images of the dry river-beds captured by their Mars Express orbiter.

According to the ESA, the upper part of the Reull Vallis region of Mars shows a sinuous river structure stretching for more than 900 miles across Mars. The riverine landscape is flanked by numerous tributaries, one of which can be seen cutting in a steep-sided channel through the Marian Highlands before running on towards the floor of the huge Hellas basin.

Here are two of the remarkable ESA photographs:

Now the big question becomes were there any trout in those big streams?
