This image shows terrain near Mangala Valles. At the bottom of the image are two black spots that are recent impact craters. The black spots form because the craters exposed cleaner materials in the subsurface beneath the bright, dusty surface. Our image is also interesting because the surface has a criss-cross pattern formed by wind activity. Bright ripples that are oriented from the upper right to the lower left are perpendicular to the wind flow. In contrast, outcrops that have been eroded by the wind are oriented perpendicular to the ripples to produce the criss-cross pattern we now observe. https://photojournal.jpl.nasa.gov/catalog/PIA24146
