36. Tuesday 12 April 2011

For our last session surveying Bull Pasture, we had two teams. Pauline, Helen and Vera set up their drawing table twice to finish off the tape offsets and triangulations surveying, while Jane and Peter completed their alidade survey. After lunch, Peter and Jane then used "Bob", the total station, to plot in a larger area.

And so the survey of the three fields was finally wrapped up and we said goodbye to Bank Fields for the spring. Now we wait for Roger to collate and interpret the results, and decide if further investigations are needed in the future.

UWHG members can now focus on a summer of the farm buildings survey, excavations at Chapel House Wood, the Wilderness Beck Grotto project in Skipton, and the production of our report on the Whitfield project in Embsay. Jane Lunnon

32. Tuesday 8 March 2011

The day was cold but fine, and we had another good turnout to work with Roger on the continuing survey of Grassington's facinating earthworks.

We began by looking at the results of last week's work, with Total Station results now plotted and the geophysical survey available. Ruth and Paul then set out careful "hachuring" of last week's work with the Total Station, before extending their topographical survey. Jane and Peter continued their work with alidade and drawing table. Helen, Pauline and Vera did more geophys.

Their work last week had identified part of what might be a circular stony bank so grids were laid out to re-survey the area, hoping to capture the whole.

It often seems to be the case that getting the equipment set up is the most difficult (and longest-lasting) part of the day. Getting the grid properly measured for geophys. on hilly terrain, getting the alidade perfectly level on the drawing table and in exactly the right position....it's not as easy as it looks, and they never show it on Time Team! Roger's expertise was heavily in demand.

But eventually we were working again and by the end of the afternoon we'd covered just about all we'd hoped to do at the morning's planning session. Another good week.
