I was just recently reading about interior mountains (central peak) within impact creators on the moon. As I recall (be on guard) I remember one writer saying that there were no interior mountains in creators less than 60 miles across. It seems that it takes a certain amount of size hence pressure to create a central peak. Just seems interesting that Upheaval Dome is barely 3 miles across and has a central peak, or does it? Maybe it is just the angle of Kurt’s photo. Jim Gibson
