Colourised crop from one of today's HiRISE releases...

Any geological types want to hazard a guess what this is? Crater with multiple rims, maybe? (I'm not good at whether a feature is an innie or an outie.)

I love the combination of slope streaks and dustdevil tracks! It's a smoking gun of sorts.

hmm, looks like craters that's been eroded down to their "cores". The boulders could be megabrecia.

alternatively, could be eroded, heavily jointed basalt... In which case you are looking at the tops of plutonic dikes.

Either way, lots of erosion.

Not so much. I meant the DD tracks are second very visual indication that a lot of dust moves around in the atmosphere, and dust avalanches can occur when things get past the angle of repose.

That is amazing. It looks like a blanket with an artistic pattern.

are the dunes in valleys?
are the surrounding terrain hills?
and mars has a thin atmosphere
do the wind cyclones die as they leave the valley and terminate at the tops of the hills?
of course the counter argument is on earth the valleys would be cold at there floors this must not be the mechanism on mars for energy for a cyclone or tornado.
tornadoes on mars must be driven differently then on earth

This one just gets more fascinating every time I look at it; definitely one of HiRISE's Top 10 most beautiful & intriguing images!

Stu, that's not resolving; can you check your source? I think there should be six digits in the first cluster of numbers.
