Mr. Geoff Knupfer:

Unfortunately, we cannot survey the entire area of the bog, simply because of the scale of the operation. It comprises several square miles or square kilometres of bog. From an archaeological point of view, we can separate out survey and search, two quite different matters. A survey could involve, for example, walking and line-searching the bog for anomalies, the use of cadaver-detection dogs, geophysics or, most commonly, ground-penetrating radar. At one time or another, we have used all these approaches on Bragan Bog, but when it comes to the end of the line, there is only one way to be 100% certain, namely, by physically searching the ground. We have done that, as we mentioned, over 21.5 acres, an enormous area to search. The bog is open, and if any members wish to inspect it at any time, we will be more than happy to host them on it. It is a vast area and we could not contemplate undertaking such an exercise on the entire bog. It is just too big.
