Contrast-adjusted crop of the Chocolate Hills to enhance the cracks and fissures. Filtered images 2 and 5 were combined and heavily played with:

The blueberries on their stems are funky!

Noway those structures could've pre-existed prior to impact. Blocks got ejected. Failure along regions of surface "defects", putting blueberries at the crack margins. Then slow sand ablation leaves the blueberries at the end of stalks. In 10E(quoi?) years the stems will fail, and the blueberries will drop, and the stems will get ablated down to the rock surface. So given an average blueberry diameter of 4 mm. Those stalks are about another 4 mm. Assuming the blueberries started with the tips flush at the crack margin, there has been 8 mm of erosion since block emplacement. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Yes, but it looks like a complicated problem, since the blueberrys on stalks (at least the ones that we can see) are in the niches that are comparatively sheltered from the erosive action of the wind.

The latest Oppy update said we're approaching some ejecta blocks to possibly use the IDD on - perhaps Chocolate Hills? The update also had this little tidbit: QUOTE Some of the rocks exhibit a dark crust, potentially impact melt.

Would I be right in thinking it would be a meteorite that split into two on its descent through the martian atmosphere? (I think this should be in the distant vistas thread - can someone help please!) Neil

One rule for arm-waving is not to stop with the first idea that comes along, but to look at all the other possibilities as well. Multiple working hypotheses! Then we can try to weed out the weaker suggestions with observations or other approaches. Phil -------------------- ... because the Solar System ain't gonna map itself.
