Frosty Dunes Near Bosporos Rupes

This Southern autumn image captures a view of frosty dunes. The sunlight is shining on the dunes from the upper right.

The low sun angle creates large shadows from these dunes, making for a dramatic picture. Frost is visible in the shadows of the dunes that appear as lighter or bluer swirls in each shadow. Along the illuminated section of the dunes, in the center-right of the image, five dark thin dust devil tracks are snaking their way along, parallel to the dune ridge. (North is to the left in this image, the image height covers 1.2 kilometers of the Martian surface.)

Note: These dunes are located just to the east of Bosporos Rupes, which is to the northwest of Argyre Planitia.
