So I finally got everything coordinated and gave it a shot.
I had about 350 pieces of slab wood delivered (pieces average about 9' long and 9" wide by thicknesses varying from 1/2" to 3").
I hired 5 guys to help me cut them down to 5 and 6' lengths (the varying width of the path), and shuttled load after load with my ATV and little rubbermaid trailer about 4000' back into the woods (through mud, hills, rocks, etc.). Got about 3/4 of the path done before the little rubbermaid broke.
As the path was made, I drove over it with the quad and the trailer to bring the wood to the end of the path. It was a hard and bouncy ride, and occasionally the wood pieces slipped out of place, but we did NOT sink.
So now I've got to figure out how to get the rest of the wood (probably about 120-140 pieces, or about 4,000 lbs) back to the path.
Most of the wood is sitting right on top, while some pieces just sank right in, requiring several layers (those were a very small percentage of the total number).
Here's a picture. I was way too dirty, cold, achey and tired to stop and take a bunch of pictures.

Thanks to everyone so much for the guidance and help with this. I'll post again when there's more progress.
