Over a winter, sleet and ice have inexorably lonesome a dunes. Unlike on Earth, this sleet and ice is CO dioxide, improved famous to us as dry ice.When a object starts resplendent on it in a spring, a ice on a well-spoken aspect of a dune cracks and evading gas carries dim silt out from a dune below, mostly formulating pleasing patterns. On a severe aspect between a dunes, ice is trapped behind tiny easeful ridges.

NASA’s Jet Propulsion Laboratory, a multiplication of a California Institute of Technology in Pasadena, Calif., manages a Mars Reconnaissance Orbiter for NASA’s Science Mission Directorate, Washington. The HiRISE camera was built by Ball Aerospace and Technology Corporation and is operated by a University of Arizona.
