More model information3 December 2019. This is a large boulder of schist, 4.2m x 3.0m x 2.8m high, of varying composition and including bands of needle-like crystals (probably amphibolite). There are about 30 cup marks. The surface of the boulder is weathered and rounded and it is likely that some, at least, of the cups are natural, or have been enhanced by weathering.
