Howdy folks! Hmmm, someone tell my eyes are deceiving me... but anyone notice conelike formation near the hills top/right of pic? Looks kind of interesting. Be kool if was some sort of venting structure for sake of geologic variety and in terms of biological potential could liven things up. Wonder if it's related to the differing black dust acquired by boneville over the generic basaltic sands found thus far in most other places in gusev?

Darn good catch...reminiscint of the cinder cones in the Owens Valley in Eastern California, or the Amboy crater out along old Route 66 in Southern Cal.

great photo...reminds me of a glacier deposit with atleast one surface of these rocks seeming kind of smooth and they appear to be in some kind of line (perhaps indicating the direction of the glacial flow)....no reason to think they dont also have geothermal events on Mars like on Earth, and I would think there is plenty of heat at Mars' core to sustain those type of events....It probably has plate tectronics also which could account for the emergence/disappearance of mountains and buttes.
