Massive floods more than 65 meters high once flooded the surface of Mars.
This is the result of a new study stating that many of the rock deposits on the red planet are the result of large moving waters, not just a "measly river."
Researchers say that Mars could once have been home to a global ice similar to the one that existed on Earth during the Pleistocene, and there were massive eruptions that shaped today's features.

According to the new research, four units within a rock section at Gale Crater represent different types of deposit, and "all these packages involved water." The researchers say that there were major floods
In the new study, the researchers studied a 400 meter long sedimentary rock found in the Martian Gale crater.
The region was explored in part by the Curiosity Rover and the Mars Reconnaissance Orbiter, and contains rocks estimated to be 3.7 to 4.1 billion years old.
Four units within this rock represent different types of deposit, according to new research, and "all these packages involved water," says Ezat Heydari of Jackson State University.
At one point, the so-called Hummocky Plain Unit, elevation edges with round cobblestones and cross beds were found, which were 4 meters high.
There the sediment grains grow up to 20 centimeters.

"These ridges are asymmetrical," says Heydari. "In other words, they were formed by a directional current."
According to the researcher, creating such features would require large-scale flooding with a water depth of 10 to 20 meters.
"That's one of the reasons why I say that these deposits are more likely to be flooded than a musty river," says Heydari.
The sedimentary rocks seen at Gale Crater may have been transported through processes similar to those that occurred thousands of years ago during the Pleistocene on Earth.

HOW DOES A LAKE ON MARS CHANGE WHAT WE KNOW ABOUT LIFE ON THE RED PLANET?
Liquid water is known to be one of life's key components, and we've known for decades how scientists are looking for it on Mars.
If there is a large, permanent body of water on the red planet, there is a good chance of producing microbial life.
Researchers had long speculated that there was liquid water below the surface of the planet, but solid evidence was lacking to confirm this.
A recent finding from an Italian research team suggests that an underground lake spanning 20 km is hidden beneath the Martian South Pole.
The discovery is the first evidence of a lake of liquid water on Mars that still exists today – an environment that scientists believe is ideal for the growth of life.
While the lake exists at an enemy temperature of -68 ° C (-90 ° F), microbes could grow there, as in similar environments on Earth, scientists said.
Dr. Brendan Burns, a microbiologist and astrobiologist from the University of New South Wales who was not involved in the research, said, "Although the surface of Mars is inhospitable, there is a fascinating possibility that microbial life in subordinate regions can survive and thrive. Glacial waters of Mars. & # 39;
"On both planets, one hemisphere was covered in ice – the Earth's northern hemisphere versus the southern hemisphere on Mars – and the other hemisphere was warm," says Heydari.
The new report is based on studies released earlier this year that allegedly provided the first evidence that liquid water still exists on Mars today.
Scientists at the Italian National Institute for Astrophysics have revealed the presence of the underground reservoir this summer.
The team says it spans 20 miles (20 km) and is buried a mile (1.6 km) below the surface.
However, studying this function will not be easy.
From now on, the technology on the Mars Rovers and Landers can not drill deep enough to reach such a deeply buried lake.
