Firefox does not react to IC here (reports it is clean) but it is never
wrong to scan web stuff. It is my standard procedure for everything
coming from outside.
I think you will like IC.

The short answer, for both features: Lunar Rills --> either collapsed or
not, lava tunnels.

Superb. With a jet and its contrail superimposed (just for scale) we would be
hard-pressed to discern a difference from a real late-afternoon photo, made with
a telescopic lens.

On the infallible internet, I've read that such features are caused by roving
herds of Moon Calves munching on moon dust-- with the resulting 'production' of
methane clouds. Stinky methane wind, a little-known secret of the Moon...

Of course. One of those facts which are hidden from us by those who know
better and live for the sole reason of keeping us in utter ignorance. I
hail your courage in speaking out.

Yep, gotta scan everything. Even known sources of software and media, because
you never know if a site has been temporarily compromised. (But when it comes to
/truly/ devious malware there's nothing we can do until all the scanners are
brought up-to-date. Even now, something malicious could be lurking in a corner
of the system...)
> I think you will like IC.
I already do. There was no fuss whatsoever when saving the png file. It did take
longer than expected, but then again it was an awfully large file.

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

But it's not close enough, since a dedicated individual would eventually observe
how the craters don't cast proper shadows near the terminator :/

Okay, I wasn't going to say anything for fear of being ridiculed. But this
proves correct my earlier hypothesis: cows are a native moon species. They eat
dust, not grass. This explains all the cheese you can find there. And they never
actually jumped over it, they jumped /off/ of it! Things will never be the same
after people hear about this...

there is that fundamental paper:
Wallace & Gromit (2002): The British origin of the Moon: The WensleyDale
Hypothesis,- Annals of Lunar Research, vol.53(2), p.1015-1037.

It /was/ the short answer ;-)
There probably is happening more than just rills indeed, but I don't
know what they could be. There are features that look like lava flows,
like in the upper part, against the terminator, and seemingly coming
from a (impact) crater. Could you point out those things you see? I am
unable to relate them to something I recognise.
Otherwise, what does NASA say about it all?
