A large sub-rectangular cutting to the north of the Greenhill clayworks (MDV 5169) at Crossways, is likely to have been associated with clayworking. The cutting is up to 54 metres long by 20 metres creating a level terrace with scarps to the west, east and south sides but open to the north. Most of the spoil was removed via the north and dumped just down the slope, on level topped finger dumps. A low curved revetted bank has been constructed across part of the north side, partly enclosing the level area. The feature is not depicted on any Ordnance Survey maps but one of its spoil heaps overlies a section of the Zeal Tor Tramway, effectively blocking it, which would date it to later than the 1870s. Its purpose is also unclear but with a deliberately levelled floor it is more likely to have been a base for a building for clay refining processes rather than extraction, though this cannot be confirmed, as no evidence of either has survived. It is possible that it was the intended site for a set of settling tanks , but never used, or perhaps timber mica drags. A silted ditch can be traced from the open end of the cutting, 135 metres south to the upper mica pond at Greenhill Works, implying that some form of waste was flowing from it.
