The word »cairn » is derived from the Scottish Gaelic meaning stone man. It can conjure images of purpose, faith, and a spiritual journey. Cairn building is a popular activity in the backcountry. It’s easy to see why people are drawn to these tiny piles of flat stones that can be stacked like children’s blocks. With shoulders aching and black flies buzzing around ears, hikers will survey the stones before her, and then try to select one that has just the right mix of flatness and tilt, breadth and depth. After a few close-calls (one too big, one too small) A true skeptic will select the one that fits perfectly into place. The second layer of the Cairn is now complete.
