Nice image of layered rock. (http://qt.exploratorium.edu/mars/opportunity/pancam/2004-05-29/1P139114667EFF2815P2531L7M1.JPG)

Any geologists want to comment on this. What is the crossbedding consistant with?

Cross bedding is consistent with water, wind and base surge from either an impact or a volcanic eruption. Given the relative steepness of the cross beds and their 5-10 cm scale I would go for water as the most likely.
