> Very few Maya constellations have been identified, and even in these cases we do not know how many and which stars exactly composed each constellation. It is thus impossible to check whether there is any correspondence between the stars and the location of Maya cities. In general, since we know of several environmental facts that influenced the location of Maya settlements, the idea correlating them with stars is utterly unlikely.

I didn't know about the relic milpa idea. I guess if there were a lot of thick solid fertilizer just in that rectangular area that wouldn't run off easily, it could possibly do that.

I think someone should check it out to be sure.
