Hi Larry, Thanks for that! Yeah... I was wondering about it from the whole 'size matters' perspective. For example: can a 500m crater be a complex one... can a 1km crater be one... or are we talking more like 3km, 5km or more?!?!?!

Hi Jeff: It has been some time since I studied this (will ask around here at the Lunar and Planetary Science Conference), but I think that it is basically: size matters! How big of a hole can you maintain in a bowl shape before gravity and the strength of the material take over?
