Migration of the Moon?
At the moment I'm trying to figure out some aspects of the Georgia Guidestones. Before I start analyzing the 10 "commandments" written in 8 languages on 4 huge stones, I'm focusing on the construction itself.
I know that you can see Polaris through a hole in the central column, that there's a hole in the roof for the sunbeams to indicate the current day (roughly), and that there's some sort of letterbox to check the solstices.
But I also found the following on the actual website:
"The four large upright blocks pointing outward are oriented to the limits of the migration of the moon during the course of the year."
What exactly does this mean?
Most of the planets follow an orbit that is pretty close to the ecliptic - the path of the sun. But the orbit of the moon isn't oriented in sync with the ecliptic. It passes north and south of the ecliptic about twice per month - and by many degrees. And if you consider that the sun itself is pretty far south in December and north in June, this adds up to quite a range of north/south for the moon over the long term.
I don;t have the exact numbers, though.
If you look at timezone master, the small skyband indicates what side of the ecliptic the moon currently sits.

Thanks for this info!
"Migration of the Moon", as stated on the given url, possibly isn't the right term since I only found websites with info on animals migrating North or South along with the time of year.
Still I wonder how one can mark this migration of the Moon using upright stones...
