Still no large rocks perched precariously.
I can accept that Mars is not Geologically active, Ie Plate tectonics, Mars Quakes etc.
I also know there is a whole lot of the planet yet to be explored.
I haven't seen any large boulders perched precariously on top of weathered rock, however it might have been weathered, I do not argue the point.
It is interesting to note what one has not seen as well as what one has seen.
I understand that such stuctures are an indicator of the lack of Quakes, at least large quakes.
So far Mars looks pretty level to me.
