Cairn Traditional Cache

Cairn is a man-made pile (or stack) of stones. It comes from the Scottish Gaelic: càrn (plural càirn). Cairns are found all over the world in uplands, on moorland, onmountaintops, near waterways and on sea cliffs, and also in barren desert and tundra areas. They vary in size from small stone markers to entire artificial hills, and in complexity from loose, conical rock piles to delicately balanced sculptures and elaborate feats of megalithic engineering.
