The making of cairns, or the single stones through the stony rugged landscape of Scottish islands can also mark the pathways to the shielings and peat cutting areas.
Totally agreed Moss. I've an uncle that lives near New Pitsligo moss in Aberdeenshire and until recently he used to cut peats. His mother in law's family lived in this croft for heaven knows how long but I would guess that the paths and path marker stones have been there for hundreds of years.* moss being the term for a peaty area.
