AIM’s Total Station (clever optical measuring device) recorded 111 readings. We spent some time looking for two Temporary Bench Marks (TBM) that had been inserted in 2002, but we could only find one; although one is better than none at all!

We needed to record the corners of both fields and the start and finish of the footpath fairly accurately; we then filled in some measurements between these sometimes lengthy distances by taking readings every 20 or 30 paces. Despite this time saving short-cut, we still took over three hours completing the task.

Now we have a good and accurate map of the valley, we can plot any features on it, such as those dowsed on the 5th of October. If we investigate these findings in the future, we can record them directly and accurately onto our survey map.
