  1. An 800 TON stone. And I had trouble getting a 1 ton steel beam 10 feet in the air with 6 people (and no modern machinery). Absolutely amazing. There is SO MUCH we don't know about the past. I have been saying for years: most cities even today are near an ocean shore or a river. Being that the sea level rose dramatically over the last X thousand years and the first cities to be submerged would be those near shorelines, my bet is there are LOTS of ancient cities underwater, possibly lost forever. Who knows? Maybe an 800 ton stone is laughable to what may remain hidden.
