This stunning image shows us the result of sublimation, as a solid converts directly into a gaseous state and disturbs the darker subsurface material. The wind then blows this material about, helping to create these eerie-looking dark spots.

Image is less than 5 km (3 mi) across and is 247 km (154 mi) above the surface. For full images with scale bars, visit the source link.
