A Theory, Which is Mine
No one is quite certain why the ancestral Pueblos eventually moved elsewhere, but my theory is that when they carved their media centers into the rock, they left room for their standard-definition televisions. When high-definition sets swept the Southwest, there was no room to expand to accomodate the wider TV’s and they were forced to move away and begin their carvings anew.
It’s just a theory.
The little round holes that you see are where log poles would attach small buildings to the cliff dwellings. Most of those buildings no longer exist but the rooms carved into the cliffs remain.
