Dunes ’n’ Gullies
Two previous images at this site show dunes and gullies; this is a chance to reexamine both for changes. Dunes have slip face striations suggesting recent sand avalanches; gullies are not especially well-developed, but worth a look.
Image cutout is less than 5 km top to bottom (3 mi) and the spacecraft altitude was 250 km (156 mi) and north is to the right. For full observation details including images with scale bars, visit the source link.
