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

Researchers based at Princeton University, the California Institute of Technology and Ashima Research suggest that Mars’ roughly 3.5-mile high Mount Sharp (above) most likely emerged as strong winds carried dust and sand into Gale Crater where the mound sits. If correct, the research could dilute expectations that the mound is the remnant of a massive lake, which would have important implications for understanding Mars’ past habitability.
