The weather forecast wasn’t great, but we took a chance and headed up to Great Buttway, Ashwell End, to continue our survey before the grass starts growing and we have to take a break until after the first silage cut. Great Buttway was surveyed ten years ago using a single sensor machine by Mark Noel. The survey was excellent, showing all sorts of Iron Age and Roman features. The only reason for re-doing it is that we are now able to survey at a higher data density allowing us to create sharper, clearer pictures..
Luckily for us, the rain held off and we managed to survey the equivalent of about 11 grid squares: eight whole ones and four partials. An excellent day’s work. Many thanks to Dave Minty, Nigel Harper-Scott and Jim West who joined Ellen and I today.
The dGPS I have been using has had its SIM card changed to another service provider. What a difference that made, and laying in the grid was a breeze. Amazing technology, really, and revolutionizes how easy it is to georeference surveys.
The survey has linked up the Roman settlement in the NW corner of the area with the Iron Age settlement in the middle of the plot. A road, presumably Roman, runs NW–SE across the area past the inevitable modern services.
The detailed view of the Roman site shows more enclosures either side of the proposed road. We can even see post-hole buildings in the eastern enclosure. A very pleasing result.
We are hoping to go back to the site next week. Hopefully, it’ll be a little warmer! Also look out for further postings about Verulamium and a survey in the Candover valley.
