By this time everyone else had finished their allotted tasks, so Roger was able to say that this particular field is now completed and next week we move back to the other side of the wall.

Pauline and Jane set to with the alidade – 2 vague figures in the mist on the far side of the field, while Ruth and Paul, assisted by ‘Bob’ attacked the banks in the top corner.
Having sorted us all out, Roger proceeded to plot a digital terrain map with the dGPS.

After an early lunch, having struggled all morning with the visibility, and with both the lens and the prism repeatedly misting up, ‘Bob’ decided he had had enough and refused to focus on the prism.
Jane and Pauline were also struggling with the visibility, so we decided to call it a day and retired to that nice tea-shop in Cracoe, leaving Roger alone on the hill-side to finish his map.

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.
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.

Having satisfied ourselves on that score, we dispersed to our various tasks – a geophysics survey, a topographical survey using the alidade, and another using “Bob”, our total station. Soon, the site was full of fluttering flags of all colours as the three teams set out their markers. The blue skies gave us a lovely background and we appreciated the warm sunshine all day!
