Hi Four Winds
Been thinking about your cairn rubble idea. You may be right.
This is all guesswork so bear with me. Problem how to sift 20 ton of rubble one mile. Raft of headcarry?
Raft. Pile 20 ton on raft. Take 16 people with levers, one trip one day, job done.
Headcarry. one person total load in basket say 50 lbs Walk one mile with full basket then one mile back with empty basket. 20 trips total in one day = 500lbs. 16 people =8000lbs = 8tons roughly.
Maybe you are right
Regards Gordon
