Images show Mars had sizable lake

LOS ANGELES (AP) — New images suggest Mars had a sizable lake on its surface billions of years ago, further evidence that the planet had a watery past.

Images snapped by NASA’s Mars Reconnaissance Orbiter reveal a 30-mile-long canyon where researchers believe water once flowed and apparent beach remnants surrounding a basin.

Dubbed the Shalbatana lake for the valley it was located in, scientists believe it was about the size of Lake Champlain that borders the United States and Canada.
