Until the end of the month there are guided tours of the present Ness of Brodgar dig. Went on one today and learnt that the Lochview mound is a tomb with revetments that has suffered from the whole area being levelled off in 19thC agricultural improvements. A test pit previously found scalloped and decorated Grooved Ware. Also pitchstone from Arran (found in the current excavation too, which is uncovering evidence for another chambered tomb, perhaps two).
