Thanks for the new term. I think you may be right... mostly.

However, I'm not convinced everything we are referring to are the same
structures. I looked up an atlas of known moon rilles, and the features I was
initially observing weren't highlighted on the map, nor were what I saw when I
made my first remarks things that resembled rilles in their entirety. But I'm
also not /un/convinced! Some of what I saw may have indeed been collapsed lava
tubes. But some were also on higher portions of low, sloping hills... the kind
of place you would expect a glancing asteroid to leave a mark. And the sinuous
ridges I also observed looked like dust that piled up by heavy winds. But since
I am fully willing to be wrong, I'll accept any and all corrections to my
misconceptions ;D
