Justin Cowart is a geologist and amateur astronomer living in Carbondale, IL. Justin has had a lifelong interest in exploring space, and one of the most fun ways to satisfy that curiosity has been looking at the images returned by space missions. His interests lie in reprocessing old data (which looks surprisingly good when it's run through modern computers!) and finding aesthetically-pleasing images that may not have gotten noticed otherwise. He can be found on Twitter as @jccwrt, and on Flickr.
Curiosity regularly takes pictures of the distant northern crater rim as a way to assess how much dust is in the low-altitude air. Sol 1997 shows the view on a relatively clear day. As the Mars year 34 dust storm developed, Curiosity's view of the rim vanished into dust.
