Went on Friday - after the access visit to stonehenge went to the trenches in the field to the west of stonehenge where we espied Phil Harding filming some bits for Time Team (presume another special on the Riverside project though didn't get to chat to him).
Talked to one of the archaeologists there who was very helpful - basically in the field to the west of stonehenge they have 2 pallisade enclosures which are not complete enclosures; more like 2 curved enclosures but quite big like those at West Kennet. they had only just gone through the topsoil when i got there but were hoping to get some dating evidence.
He also informed me that there was a trench in a garden in West Amesbury where they think they have picked up the avenue close to the river.
The trenches on the section of avenue near to Stonehenge are to re-excavate and extend poorly recorded trenches dug in the 1950's. They also hope to find evidence as to whether the avenue had any stone or timber rows running along it.
A further trench has been placed in the dry river bed in stonehenge bottom. they think there is some evidence the dry river banks have been artificially landscaped and are looking at the possibility that a branch of the avenue could have run along there.
will probably pop over there weekedn afternext to see what's happening.
