That is a weird-looking one. Even its shape -- from this vantage point anyway. |

QUOTE Reckless said: What turned it over is another story. The dunes we see in the image might have had something to do with it, those might move slowly in the wind direction and one part of the rock might have been covered for some time. When the dune moved on the support vanished on one side the rock might have rolled over. If there are small amounts of humidity in the sand could provide a pushing movement when the water freeze and melt, this said with the reservation that im uncertain if the sand ever will have that much humidity. We've seen just a bit of thin frost on this rover, but neither rover have shown frost covering the landscape like what we did see from Viking. So I am a bit hestitant proposing it as one explanation. |

It may have happened a very long time ago... Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!
