About this work
Gully and defrosting activity have been visible here along the edge of a dune field, along with blocks of frost. Observations from NASA Mars Reconnaissance Orbiter of the same area help check for repeat activity, as well as measuring those meter-scale blocks that we've seen prior. In this case, we want to compare any possible changes with a previous observation, which we acquired in 2011.
