HiRISE: Gullies with color anomalies
This is an oblique view of gully deposits from the steep slope of an impact crater. The deposits with anomalous (bluish) colors may reveal very recent activity, not yet homogenized by dust deposition, or there may be sand preferentially trapped … Continue reading

HiRISE: Windblown sand in Ganges Chasma
Dark, windblown sand covers intricate sedimentary rock layers in this image from Ganges Chasma, a canyon in the Valles Marineris system. These features are at once familiar and unusual to those familiar with Earth’s beaches and deserts. Most sand dunes … Continue reading
