Dunes in Becquerel Crater

Dunes in Becquerel Crater

Dunes in Becquerel
The dunes in Becquerel Crater that carve out the layered material originate upwind in this smaller crater on Becquerel’s floor. Their shape in Context Camera images indicates a more complex wind regime than the unidirectional barchans that carve out yardangs in the layered deposit to the south. Why is it different? And what is the original source of dune sand in this crater?
