CROSS-DYKE, CRUCORNEYPrimary Reference Number (PRN) : 04513.0g

Site Type (preferred type first) : Neolithic Dyke
Legal Protection : scheduled ancient monument
Garreg Las Cross Dyke, a large stone bank (no ditch), stands across a ridge at 490m above OD.There is a worked stone, a marker of some kind. The dyke could be a Neolithic work belonging to a ritual group of monuments (Las Monument Complex, prn 08452g).
Garreg Las Cross Dyke is a large stone bank, c.8m wide, on a small depth across the west ridge of Hatterall Hill, standing at 500m above OD. The dyke takes advantage of a natural scarp (1m to 1.5 in height) and is composed of fairly large sandstone cobbles (<0.4m) with a thin covering of vegetation in places. It stands up to 2m in height. There is no discernible ditch. A slight bank up to 6m out from either side of the stone bank, suggests that the dyke may have been wider. There is a footpath situated crossing approximately the center of the earthwork. At that point is a gap which is 2m wide at the bottom and 6m wide at the top, with gentle sloping sides forming a V-shape profile. At the western end, is a stone 0.55m long by 0.33m wide with a slot in the centre (0.04m wide, 0.11m long and 0.08m in depth). This worked stone, probably a marker of some kind, distinguishes itself by its position at the very end of the dyke, but neither function nor date of this stone is clear. Also, at the western end, c.20m to the north, is a post-medieval quarry (LEWIS R 2006). The dyke could be Neolithic and so would belong to a ritual group of monuments : a henge and two satellite round barrows cairns (Las Monument Complex, prn 08452g) (Olding 2000, 91).
