The Full Story
Valles Marineris is the largest canyon system in the Solar System and lies on Mars near the planet’s equator. It extends for roughly 4,000 kilometers, making it far longer than Earth’s Grand Canyon. In some places it is about 200 kilometers wide and up to 7 kilometers deep. Scientists think it formed through tectonic stretching, collapse, and later erosion rather than by a single river-cut process.
