Today’s outing a couple of hours on Cambridges Chalky side.
The massive earthwork monument known as Fleam Dyke consists of a 7-8m high bank and ditched barrier which ran for 5km from Balsham to Fulbourn. Possible extensions to it occur at both the south and north ends, and a further part of it might exist from Quy Fen to the River Cam at Fen Ditton. The main part of Fleam survives today as a footpath and parish boundary, but historically the northern part was also the boundary between Flendish and Staine Hundreds. The Moot for these Hundreds was at Mutlow Hill, a Bronze Age barrow which had clearly been an important landmark for many centuries before its use as an Anglo-Saxon meeting place. Apart from the 4,000 year old cremated burials for which it was originally built, rare third century BC Greek coins have been found close to the burial mound. It was reused in Roman times for a temple, and it is no accident that Fleam Dyke passes right beside it. Mutlow rests on the top of a hill, and overlooks the junction of several routeways (including the Icknield Way) where they meet and cross Fleam Dyke.
The highlight is the Osmia Bicolor male ,, but i must find the beautifully coloured female.
