Drought-stricken California is always on the lookout for water. But scientists are also on the water hunt more than 34 million miles away on Mars.

Popular theory says water on the Red Planet has only existed underground. But new information from NASA's Curiosity Rover suggests Mars may have once been wet and wild.

Ashwin Vasavada is with the Mars Science Laboratory at JPL. He says they have been trying to explain how a big mountain formed in the middle of Gale Crater. He says geological evidence, like the wet environment seen at the base of the mountain, now suggests water may have been the culprit.

"We had an inkling, a hypothesis really, that water was heavily involved inside the formation of the mountain inside Gale Crater, but only in the last year with out boots-on-the-ground inside the crater, looking at the geology, were we able to see evidence, and we saw a lot of evidence," Vasavada said.
