Terraced Craters and Layered Targets

Small impact craters usually have simple bowl shapes; however, when the target material has different layers of different strength, then more complicated crater shapes can emerge. (Audio by Tre Gibbs. Enhanced color images are 1 km across.)

Layers, Bedrock Ridges, and Dark Sand in Schiaparelli Crater

The ridge origin is a mystery, but the sand may simply be nucleating on the ridges. This suggests that some apparent large ripples on Mars are sand nucleation sites on pre-existing topography. (Audio by Tre Gibbs. Enhanced color images are 1 km across.)
