Any thoughts on the martian "Anthill"?
I've been noticing, in the Spirit images of the Columbia Hills, a dark formation out in front of them that has an "anthill" appearance. Looks like a small volcanic cinder cone. Here's a 3D image that shows the feature rather well:
Columbia Hills Sol 120
Here's the same picture without the 3D
Same shot, no 3D
In both pictures the feature I'm talking about is on the right side of the image at the base of the hills. Curious what the geologists in the crowd think of it.
