Field survey update

The survey plot (left) is the latest one available - it's taken a while to put together as there is a lot of data to process. It shows the two parallel linear features clearly, running North/South from one end of the field to the other, over a distance of 324m (it's a big field!). You can also see a series of horizontal lines running East/West, which are thought to be the remains of ridge and furrow.

I estimate that a further 6 grids will be needed to finish off the "Roman road" survey. To see if and how far the ridge and furrow remains extend, a large area of the field will have to be surveyed (maybe up to 40 grids!) but this depends on time, good weather, survey method and our enthusiasm for the task.

Andrew Hall isn't aware of these results yet. I hope to see him soon to bring him up to date. Maybe broach the subject of excavation?

Field survey update

Six & a bit grids surveyed today. The whole length of the road/track from top to bottom of the field has now been recorded. The filling-in detail has started to pick up the lefthand linear feature, which can be seen on the left of the survey plot.

Field survey update

The forecast rain held off. Yippee! Another 4 grids surveyed. Jon Kenny suggets that the horizontal features (left & in previous blog) could be the relicts of ridge and furrow. Further investigations required. Going out again tomorrow (Wednesday) to survey the last 4 grids to complete the survey from one end of the field to the other.

Field survey update

Six more grids completed - 8 to go. Six horizontal linear features identified - could be field drains? The vertical linear feature is a continuation of the righthand feature seen on the previous survey plots. The lefthand feature is just visible in the top left corner. Additional grids will be surveyed to the left of this area in order to pick this feature up again.

Field survey update

Another full day in the field and 6 more grids surveyed. Results indicated the "road" continued on its southward track but curving slightly to the west. The two parallel features can still be seen on the left of the plot. The lighter grey area over most of the plot represents relatively low resistance which could be interpreted as a large expanse of wetter ground conditions - it could be geological rather than man-made. Another place to dig in the future!

We have to wait now for a few days before we can go out again 'cos of the rotten weather.

Field survey update

Wednesday 3rd saw another day in the field. Although it was very hot and humid, Sue May & I managed to get 2 1/2 grids recorded. The results show more field drains (3 horizontal lines) and a definite (vertical) feature that seems to line up with the similar one towards the top of the field. The survey just done is at the bottom end of the field adjacent to the hedge.

July "Geofizz" Meeting.

An unexpectedly gorgeous Wednesday evening saw the group learning the black arts of "resistometry" under the careful guidance of Jon Kenny and his apprentices. Fortunately we got a result from exactly where we expected one! Our suspected Roman road was running true to form in an exactly straight line. Thanks to Alan for organising the event, and, if anyone would like to volunteer for further geofizz work then Alan would llike to hear from you.
