Canyons and cliffs
I have been posting a lot of Earthbound posts recently. To take a break from Earthly pleasures, I shall post some extra-terrestrial photos too.
I came across this magnificent picture of some cliffs at Mars' north pole. They are 2km high! Fantastic!
But not the biggest in our solar system. On planet Earth it is not the Grand Canyon that is our deepest canyon, but the Colca Canyon in Peru, where the cliffs drop over 4.5km deep.
But even they pale into insignificance when we look at Verona Rupes on Uranus' moon Miranda. We have cliffs a staggering 2okm high!! Boy I would love to see an up-close photo of them!!
