Quarries. - S8.E28

Dynamite explodes hills to bits, drills divide sheer stone walls, 400,000-pound blocks are pulled from pits by giant cranes, and men work around the clock to wrest rock out of the earth. Not diamonds or gold…rock, the raw material of civilization! Without rock, modern society wouldn't exist. Roads, sewers, dams, bridges, buildings, paint, glue, make-up, antacids, and even chewing gum need crushed stone. From ancient days to the present, we explore the evolution of quarrying techniques.
