This standing cairn stone, pictured below, was the first large stone recovered from the Garden Site. It has four sides, representing the cardinal directions: north, east, south, and west. It rests atop the boulder below it, with a marker to help position the stone correctly.
Interestingly, this standing stone can be laid horizontally spanning across the two larger base-stones, forming a triangular opening between the three stones. This opening faces directly towards the winter solstice midday sun, suggesting that there might be additional stones just north of the site, where the sun might shine onto.
