PIA04768: Small Syrian Volcano
This image from NASA's Mars Global Surveyor shows a volcano and surrounding terrain on Mars that have been thickly mantled by dust which had subsequently been eroded so that it appears textured rather than smooth.

MGS MOC Release No. MOC2-498, 29 September 2003

Today, 29 September 2003, is the first day of southern summer, and the first day of northern winter on Mars. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a small volcano in Syria Planum near 12.9°S, 102.7°W. The volcano and surrounding terrain have been thickly mantled by dust; this dust has subsequently been eroded so that it appears textured rather than smooth. The thin, light streaks that crisscross the image are the tracks left by passing dust devils. Not all dust devils on Mars make streaks, and not all streaks are darker than their surroundings--those found in Syria Planum are invariably lighter in tone. The picture covers an area 3 km (1.9 mi) across; sunlight illuminates the scene from the upper left.
