Mounting Evidence of Martian Rivers in Long-Term Action
Scientists have long theorized that in its distant past Mars has had water. New evidence provides substantive evidence that rivers may have been roaring on Mars for a very, very long time. More from SlashGear:
…a team of scientists has discovered the stratigraphic product of multiple extensive fluvial channel belts in an exposed vertical section at a location called Izola Mensa in the northwestern rim of the Hellas Basin. The rocky cliff is 200-meters high and provides evidence of an ancient watery landscape.The cliff has sedimentary rocks that are 3.7 billion years old and performed by rivers that were likely active for over 100,000 years of Martian history. Scientists say that the extremely high-resolution imagery allows them to “read” the rocks as if they were standing close to the cliff. The team notes that they don’t have the ability to climb and look at finer-scale details, but the similarities to sedimentary rocks on Earth leaves “very little to the imagination.”
