This observation is part of a long-running image campaign to aid in the classification and volume estimates of dunes in the U.S. Geological Survey global dune database. Sand dunes are among the most widespread wind features present on Mars. An earlier image from 2017 showed intresting height vs. ripple wavelength trends, but we need a digital terrain model to assess.
