Hi floyd,
we have seen what a couple of million years of low density Mar's wind can do to 'fluted' rocks. I think the environment there is alien enough that we cant quite appreciate the processes On Earth you be hard pressed to find a dozen 'craters' due to fast (compared to mars) erosion (rain, winds, quakes, tectonics, oceans) These could be stream cobbles or wind eroded ... I am waiting on Grotzinger .et al to weigh in. But it sure is fascinating! Awesome image! See you around town, fellow Bostonian! -------------------- CLA CLL
