The reason i had thought this picture strange as i am aware of what lavatubes look like is I never knew they would follow a crater lip...
when the crater hit the moon, the crater lips form like a upheaval and the depth increasees, so the crater lip would be thicker ground would it not?
so then that would tell me that in order for the lava tube to be along the same path as the crater lip, it would have to be formed after the crater
was formed. So is it then possible for a lavatube to be formed on the lip of a crater taking in the consideration that the ground would be thicker? if
the metorite hit the ground there, i would think the lavatube would be collapsed in a more non-uniform patter rather then a arc around the lip.
Also the lava tube collapse isnt that far down because if you follow it down where it curve around the lip of the first crater, it ends dramatically
on a smaller more recent crater that isnt as deep as the original.
correct me if i'm wrong .. just seems weird that lavatube would follow (even partially) the lip of an ancient crater.
