HiPOD: Dune Avalanche Slopes

These dunes have exhibited recurring slope lineae (RSL)-like streaks in a couple of previous images, but they do not seem to have been significant in 2013, when we obtained a full monitoring series. With this observation, we can keep monitoring to understand this activity, which may help test the RSL-granular flow model for the streaks.
