On the first day I arrived early and marked out the 12m by 10m trench.
Lee the digger driver arrived, put on a flat edged bucket and we watched as the garden and ploughsoil was scraped off and placed to one side with just few centimetres above the chalk.
We found clay tobacco pipe stems and willow pattern ware right down to the natural chalk surface.
Today we formed a line and worked backwards from the NW (compost heap) end of the trench and revealed the chalk bedrock cleaning and revealing the white blocky surface.
Chalk is nice but for the first 5m of our trench was that’s all there was… no archaeology at all. My imagining of an intricate intercutting, multi-period feast of the past was not working out.
Then the chalk disappeared along a curving edge and by the end of the day a 2m diameter pit and a couple of post-holes had been revealed. We hope for more by Digging for Britain turn up tomorrow.

I’m looking forward to visiting on Friday and hope that you are successful in finding evidence of the second half of the Flagstones enclosure. This whole line of monuments from Mount Pleasant through to Maumbury Rings is so important and I hope that English Heritage do some day grant Flagstones Scheduled Monument status but I’m sure it’s a lot of work to achieve that!
