The Charlevoix impact crater

collapse

Figure 12: VERY simplified cartoon (not to scale) demonstrating crater collapse with local shortening as material is transported into the bowl. Cartoon adapted from Figure 5c of Melosh (1999). Dashed line is crater rim prior to collapse. Blue line is final geometry of crater. Red lines and accompanying arrows are faults/material motion.
