Picard Crater |LROC Moon


Picard crater, at 14.55° N, 54.74° E, exposes a chemically distinct underlying basalt layer in Mare Crisium.

Cracks in a terrace on Picard crater's wall indicate the terrace was flooded with impact melt. The cracks probably formed during cooling of the impact melt as it solidified. LROC NAC M1107917713RE, image width is ~1300 m.
