Glenballoch Standing Stone
AKA Craighall or Glenballoch Cottage
Walking up to this monster monolith from the nearby stone circle, this stone simply dominates the horizon. It’s huge. 2.5 m high by a maximum of 2.6 m wide. Round on its east side, near the base, are six, possibly seven, cup marks- difficult to see as some of them have eroded over the centuries. However, there are four extremely deep (about 4 cm) marks set in a square- two 7 cm and two 5 cm diameter cups. It just seems so blatantly obvious to me that this is a representation of the circle seen from here only 200 m down the hill.
