Dulovo Crater Region Barchan Dunes

Dulovo Crater Region Barchan Dunes

Beautiful Barchans
There is nothing like barchan dunes, especially Martian ones. As sand escapes over the top of the steep side, it forms a trailing wall that is not steep, extending further backward. If there is a substantial change in wind direction, the crescent form can be destroyed. This dune field is located in the 18-kilometer wide Dulovo Crater, is near the Martian dichotomy boundary that separates the ancient terrain of the Southern Hemisphere from the much younger lowlands of the Northern Hemisphere.
