A Day at Valles Marineris: One of the Largest Canyons in the Solar System

If you’ve been to the Grand Canyon, then you probably know what it’s like to feel rather fleeting and smallish. When you stand next to this vast trench, you see an immense structure that’s been some 70 million years in the making (which is a bit longer than the 7 decades most humans are allotted). The canyon snakes across Northern Arizona, stretching more than 270 miles (434km). At points, the chasm is more than a mile deep (1.5km). However, impressive as the Grand Canyon is, it doesn’t come close to measuring up to Mars’ largest canyon, Valles Marineris.
