Landforms in Arcadia Planitia
Landforms in Arcadia Planitia
Wind continues to shape the lowland region of Arcadia Planitia today. One terrain ridge acts as an obstacle for dust-laden winds, which deposit dark, volcanic sand there ('dark deposits'). The extensive reddish areas consist of countless yardangs; to see them, you must zoom in to the image's resolution limit of 18 metres per pixel. The view is particularly remarkable because it captures several 'dust devils'. At the lower right is a 15-kilometre crater whose ejecta blanket indicates volatile-rich components in the subsurface that have liquefied the ejecta (a 'fluidised ejecta blanket').
