Opportunity is not quite at Victoria yet, but on the horizon is a tantalising goal for the future- the big eroded crater to the south-east, the rim of which is already visible. This is the first 'large scale' topography of the mission so far. Wouldn't it be great if Opportunity could get to these hills and uncover their secrets?

-the dark channel-like features are most probably basaltic-sand dunes. Nico Any chance you could link a pic of a terrestrial equivalent? While I don't doubt that they are basalt, I've looked around for dunes similar to these, without any luck. The only terrestrial feature that I've found (so far) that resembles these features is eskers or collapsed lava tubes. Any chance they could be eskers? They don't look much like collapsed lava tubes. I found a LPSC2006 reference to eskers on Mars - apparently they're not unknown: http://www.lpi.usra.edu/meetings/lpsc2006/pdf/2035.pdf Another reference I stumbled upon while googling "sinuous ridge" was to trapdoor faulting in a volcanic caldera. This seems also not out of the question as an explanation. Could really use some more hires pics. |
