A late 1980s (we’re still trying to track down the exact date) video from Jeff Hodges of Martin Brecht and Jim Baker discussing the origin and meaning of the corbeled stone chamber at Mead Farm as moderated by Ray Singer. As you’ll see from the video, the alternative views on these marvelous structures from a quarter century ago are just the same as those offered up today.
Many thanks, Jeff, for sharing this with all of us.
