Many parts of Chaco Canyon can be reinterpreted to mean very different things from the official archaeology.
To start with, it was the center of a major transshipment route all the way from New England to South America. Perhaps comparable to Chicago today. It was also something of a “banking center”, in that at the time the reserve trading currency was turquoise chips, tens of thousands of which have been discovered there.
Something that can be noted on the site are the many underground “kivas” or rooms, or at least that is the assumption, until you notice that adjacent kivas are stair stepped down, so may have instead been cisterns.
The buildings there often have basements, as well as several floors, and the different construction masonry techniques are very obvious.
About halfway from Chaco Canyon to Albuquerque is the Petroglyph National Monument, a black basalt mesa cliff face with some 24,000 petroglyphs on it. Perhaps it was the Free Republic forum from a thousand years ago.
FR has been having its own problems with indecipherable petroglyphs of late.
