HiPOD 14 April 2020: An Active Gully in Matara Crater

Gullies in the sand dunes of Matara Crater are very active. One large gully in particular has had major changes in every Martian winter since HiRISE began monitoring, triggered by the seasonal dry ice frost that accumulates each year.

This time there was an especially large change, depositing a huge mass of sand.
