Also reading the David Field one Earthen Longbarrows, which is very good, notice from the excellent aerial photographs that the Old Ditch longbarrow (longest in Wessex at 120 m) has not been photographed on here - is it on Salisbury Plain i wonder?, and there's a lovely reconstruction painting by Mike Codd of Nutbane longbarrow...
From an aerial perspective, EKLB is totally different from WKLB, but similar to the Beckhampton one...
