[Rockhounds] moving rocks...

[Dennis Buffenmyer]

List,

I need to ask a favor of the list. SOME time ago.... there was a posting 
of a link with a video of this guy who found very simple ways to move 
rock, including placing a very small pebble under a large boulder and 
moving, to ( I seem to recall ) rolling a rock up hill by putting 
notches in the uphill portion.
I tried looking in the archives but my memory cant even recall WHEN I 
may have seen this. ANY help?? ANYONE?? I need to implement one of the 
processes...
