DescriptionPSP 007073 2030 (38301927295).jpg	Duricrust. While it sounds like industrial product, “duricrust” is a hard mineral crust formed at or near the surface of soil in semiarid regions by the evaporation of groundwater. Investigating this for past water is a good rationale for future exploration. NASA/JPL/University of Arizona (283 km above the surface.) www.uahirise.org/PSP_007073_2030
