Blog Post Image: New analysis suggests wind, not water, formed mound on Mars

The researchers report that air would have flowed up the crater rim (red arrows) and the flanks of Mount Sharp (yellow arrows) in the morning when the Martian surface warmed, and reversed in the cooler late afternoon. The researchers created a computer model showing that the fine dust carried by these winds could accumulate over time to build a mound the size of Mount Sharp even if the ground were bare from the start. The blue arrows indicate the more variable wind patterns on the floor of the crater, which includes the Curiosity landing site (marked by the “x”). (Image by NASA/JPL-Caltech/ESA/DLR/FU Berlin/MSSS)
