Across the Sands

Observations like this one will be used to aid in classification and volume estimates of dunes in USGS global dune database. Our focus is on the wonderful dust devil tracks still visible on lighter ground that fade over time. A global scale study of Martian dunes serves a dual purpose in furthering understanding of both climatic and sedimentary processes, which are two fundamental topics currently driving Martian science.
