Hi All: Why can't these chevrons in the Mars picture just be typical sand dunes?
I happened to look at the whole picture and the lower features that look like boomerangs are called barchans and are caused by wind. I happened to actually use this picture at a workshop last week! The wind blows the dust off of the high areas on the left and creates these features.
