Researchers speculate that the system these rivers formed existed for more than 100,000 years in Mars's geological history.

Using data gathered by NASA's Mars Reconnaissance Orbiter, scientists surveyed the Hellas Basin and discovered signs on a 200-meter-tall cliff that suggests the region used to support a river system.

Writing in a news release, the team says the extremely high-resolution image from the orbiter's camera allowed them to read the cliff face and see sedimentary rocks that one would find on riverbanks.

According to the researchers, these ancient rivers probably changed their gullies and left behind sandbanks like certain rivers on Earth, such as the Rhine in Germany and rivers in Northern Italy.
