<<The larger Aureum Chaos region is a chaotic jumble of eroded terrain in the eastern part of Mars' immense canyon Valles Marineris.>>

This is one of the most stunning 3D space pictures I have ever seen! :shock:

A question regarding the spectacular picture in Neufer's link : is the vertical scale exaggerated ? Put differently, how deep are the canyons seen there ?

Similar question about the waves in to-day's aesthetical APOD.

Anything like it on Earth?

Post by PaGeN » Fri Apr 04, 2008 5:56 pm

I am trying to get a feel for what I am looking at in this picture. Do we have anything like this on Earth?
spans about 4 kilometers, a distance you might walk over flat ground in less than an hour.
Something a bit more than the reference with the picture.

TIA,

More or less, yes. The stuff growing in the pictures on this page makes it look a little less like Mars, but geologically it's similar:

No data still off the height of those sand dunes (if they are sand dunes) ?
Is ~100 metres a correct approximation ? (ap080404)
