Little more than a minute after a mid-1969 underground nuclear detonation, the ten-story tall 200-ton instrument tower was pulled along tracks by cables from above the detonation point. About 20 minutes later, the ground collapsed into the cavity caused by the detonation, producing a 175-foot crater.
