We can’t say much about this dead civilization, but they understood albedo.
Every summer they painted their village white, to reflect as much of the hot sun as possible.
Then six months later they painted their village black, to absorb as much of the feeble winter heat as they could.
Oh, one other thing is that you can say about this civilization is that it lasted exactly 341 years, and that it ended during winter.
Consider this a friendly, local pub. Make yourself at home, bring your friends, have a good time! Meet new people, have a laugh, enjoy the ambience, and the Oxford commas.
