Sand, glorious sand: Mars in high-resolution

[Just incredible. If you have a spare hour or so, go to http://hirise.lpl.arizona.edu/ and browse - and then browse some more. Each of the thumbnail images on the site is actually from a satellite pass, and clicking the "RGB color (non-map projected)" link downloads a long narrow image; I've simply compiled segments of some for this "montage." Thousands of geologically and artistically staggering images, all, wonderfully, in the public domain -  Credit: NASA/JPL/University of Arizona. A good way to mark a hundred posts on Through the Sandglass.]

Fascinating images that beg for more closer examinations by robots or humans. Congratulations also Michael on reaching 100 posts.
