Looks a LOT like wind (particle) erosion to me, Joe. I recall seeing similar terrestrial sandstone formations. Without subduction processes, maybe similar features could have formed on Mars in basaltic or volcanic bedrock? Where's Mark Dakins when you need him. C. --- Joe Bauman <bau@desnews.com> wrote:
Hi all, here's an image of Mars that Patrick sent out in his News. I just wanted to make sure nobody overlooked this one -- it's really strange! I'd like to hear your thoughts about what could have caused these formations. Go to the site and click on the small image to get a larger one. Maybe it's the bottoms of craters, where the land was compressed by great forces, then exposed when erosion wore away the overburden; or maybe it's evidence of the Martian version of plate tectonics; or maybe it's scrapings left by ice flows; or maybe it's some kind of evaporate; or maybe it's ... boy, I just don't know! Folks, take a look and throw out some ideas. Best wishes, Joe
