Attached is an image highlighting the areas I was talking about.
"A" points to three features I suspect might have been produced by asteroids
scraping the surface. Notice how they seem to have occurred on the sides or
upper portions of a (really large) sloping hill? To me that indicates they were
perhaps caused by asteroids hitting the moon at glancing angles... But I can
definitely see how they could have been caused by collapsed lava tubes.
"B" encircles the area of sinuous ridges. They do appear to emanate from an
impact site. Are they lava flows as you suggested? Or dust accumulation?

Lol, I should definitely check instead of just guessing. (But guessing is so
much fun sometimes ;))
