Wind-Exhumed Crater

Feb. 2, 2005
NASA's Mars Global Surveyor shows the expression of a formerly filled and buried meteor crater, locked within sedimentary materials eroded by wind in the Memnonia Sulci region of Mars.

The large circular feature in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image is the expression of a formerly filled and buried meteor crater, locked within sedimentary materials eroded by wind in the Memnonia Sulci region of Mars. The ridges and troughs in the image attest to the power of wind erosion to form yardangs.
