Mars may have once had an ocean and this chaotic valley is a big clue
A colossal valley near Mars’s equator is revealing dramatic clues about the Red Planet’s watery and volcanic past. Stretching roughly 1,300 kilometers, Shalbatana Vallis was carved billions of years ago when enormous floods of groundwater burst onto the surface, gouging deep winding channels across the landscape. Today, the region is a striking mix of ancient flood scars, collapsed “chaotic terrain,” lava-smoothed plains, volcanic ash, and battered impact craters — all hintin
A massive valley near Mars's equator, known as Shalbatana Vallis, is providing significant evidence of the Red Planet's ancient watery and volcanic history. This valley, stretching approximately 1,300 kilometers, was formed billions of years ago by immense floods of groundwater that erupted onto the surface, creating deep, winding channels. The area today displays a complex landscape featuring remnants of these ancient floods, collapsed regions of chaotic terrain, plains smoothed by lava flows, volcanic ash deposits, and impact craters. These geological features collectively suggest that Mars may have once possessed a much warmer and wetter climate than its current arid state.
Understanding Mars's past habitability is crucial for the ongoing search for extraterrestrial life and future human exploration.
