There are multiple dunes in this observation worth looking at! The barchan dunes might have their source in Chasma Boreale in the northern polar region of Mars that we have seen in earlier HiRISE images. Barchan dunes are notable for their croissant-shaped appearance. Our goal is to continue monitoring over several years to look for changes, the rate of changes, as well as the texture of these stunning dunes.
