Building Stone Henge? or just wanting to move heavy stuff! Logs, beams, poles...

Travis Johnson shared this video in another thread, and I thought it was worth sharing further.  In that other thread I brought up the idea of the gin pole on a tripod, but that technique is a little unstable in the final erecting stage.  This guy in Michigan is moving and standing up all kinds of really heavy concrete blocks by himself.  The keys are pivot points/leverage, gravity, and removing resistance.  I've seen a variation on this with the idea of erecting stone henge, but I think they had the stone on a ramp made of wood and dirt that was disassembled to lower the one end and slide the mass downward, but I can't find that link right now.  If anyone can find other videos or links that show this technique done by others, please post it here.

I remember seeing a show about recreating the building of Stonehenge on the History channel. Many years ago when I owned a tv. But you might try looking in their archives.

Very cool.
Did he show how to get one of these blocks that first inch or so off the ground?
Digging under might work, but this method seems to rely on a hard smooth surface for the pebbles  to rest on.

 I didn't see any other videos that showed that.  I assume that he must have dug under it so that he could gain the initial teeter totter effect and or the rolling lubricant of pebbles.  I've been onto other 'research' and haven't gotten back to exploring this.
