Formation of High-Latitude Pedestal CratersPrior to and just after an impact on Mars, a small fraction of the total impact energy is directly coupled to the ambient atmosphere. A resulting hemispherical shock wave propagates outward leaving a signature that is dependent on initial atmospheric and surface conditions. Here we propose that the distinctive pedestal craters common at high latitudes on Mars are a direct consequence of extreme winds and elevated temperatures generated by this atmospheric blast.
