RCAHMS NMRS record no. HY21NW 19 at HY22821792 is an overgrown eminence of small stones and earth generally called the Knowe of Geoso. It was [?]mistakenly thought to be a broch by association with the dwelling of Brockan in the diagonally opposite corner of a field below [itself now mistakenly placed at the quarry in the adjacent field’s corner, Brockan here being a name which like the Hillock of Breakna signifies ‘broken (hillside)’]. This turf-covered mound despite much ‘quarrying’ is still about 0.8m high and roughly 25m across, and has barely breaking the surface in the exact centre a 0.4m long slab that could be what remains of a cist. To the SE [i.e. immediate left as you come up from Skaill Home Farm] there lie nine stones of more monumental size in an arc that probably preceded the knowe, having significant weathering and not sharing a commonality of centre with it.
