I come across one of many glacial deposit stones that have been coincidently placed at the edge of an elevation drop off. One theory that has been put forward about placements of stone piles is that they were placed to represent the depictions of star constellations. In this case the three stones placed in a row behind it may represent the star constellation of Orion's belt, and the stone at the edge of the cliff could be one of the stars that make up the sword. One of the stones that formed the group of thee stones looks roughly like a dagger. Brian Ghilliotti
