Gushing flood formed giant Martian sinkhole.
LIKE water draining from an unplugged bathtub, meltwater flowing through deep cracks in the Martian rock may explain the origins of the enormous Hebes Chasma canyon.
About 100,000 cubic kilometres of material had to be removed to form the scar, which is five times the width and depth of the Grand Canyon. But where that material went has been a mystery, as there are no surface channels through which water and sediment could have exited.
Water from the canyon may have erupted onto the surface again. This would account for a nearby valley called Echus Chasma that looks as if it was carved by water, but for which there is no other obvious source. "You've got signs that a huge amount of water just erupted out of nowhere from depth and flowed down, scouring out a valley," Jackson says.

I wonder how long it will take for people to start realising that life (maybe even intelligent?) in the universe might be as close as in our own solar system.

A little bit more evidence to add to the ever growing pile

So how long has this been there? They've scouted that planet hundreds of times yet all of a sudden there is water? NASA is always hiding stuff, they been knew if you ask me. I have a feeling disclosure could be soon. Ah.. let's hope so.

what if we were the ones who lived there a long time ago and the knowage of the past was lost some how. we landed on earth and had to start all over again...
really interesting find. i wounder if there really is liquid water, is there life on mars?

What happened to water on Mars anyways? Would it evaporate on Mars? If so, where does it go seeing as how there's no atmosphere? Or did it just seep underground? Just curious because I really don't know.
There is an atmosphere (but a thin one), and the water would evaporate. The weather on Mars is such that the water vapor and carbon dioxide in the atmosphere mostly migrates to and collects near the poles, then condenses back into the polar ice caps.
