Scientists have looked at the topography of the areas where the recurring darker streaks are observed, and it looks like the slope angles match the critical value for granular flows.

The seasonal dependency is attributed to hydrated salts, small amounts of water bound in the sand, that trigger the sand flows.

It's what I always considered the case. Darker sand trickling downslope.
