Well, this should give the ancient aliens whackos something to go buggo about:

Teen Discovers Lost Maya City Using Ancient Star Maps

In short, a Canadian 15-year-old realized that the locations of known Mayan cities lined up well with the brightest stars in Mayan constellations. In proper scientific tradition, he used constellations to predict the location of an as-yet undiscovered Mayan city… and after examining satellite images, it appears that there really is a city or complex right there.

So it looks like the Mayans laid out their civilization based on star maps. If that meant building a labor-intensive structure hell and gone away from rivers and roads, expending vital resources and manpower in an effort to build pyramids in mountains, then so be it. While that’s an impressive commitment to cause, it is in the end pretty damned silly. I’ll note that the Mayan civilization vanished, swallowed by the jungle. Perhaps their strategy of basing their civic planning on superstition rather than logical use of resources might not have been so wise.

UPDATE:

Ooops. It’s looking like this is turning out to be hogwash. The “Mayan complex” looks to archeologists like an old corn field. The article linked above links to several experts who are less than thrilled that they are having to comment on what one of them refers to as “a terrible example of junk science.”
