This observation features some really nice and well-spaced barchan and dome dunes within a Meridiani Planum impact crater. We also imaged these dunes twice before, and noted changes in the second picture, so this observation can give us more to look at. Barchan dunes face the wind, appearing curved and are produced by wind action predominantly from one direction.
