Dowsing the Dales - PART FIVE


The Fountains Fell Master Cave

Introduction

Part Two of this series of articles on dowsing results with reference to cave systems in the Yorkshire Dales dealt with Penyghent and Fountains Fell (Wilcock, 1989). The pros and cons of dowsing will not be reiterated here: there has been enough of a discussion in the letters column of Caves and Caving, and a dowsing class was held at the 1992 Cavers' Fair in the Forest of Dean. My own paper "On the possible scientific justification of dowsing for the detection of caves" at the BCRA Conference in September 1992 was attended by a large audience; during the following practical class held in Bradford City Centre, novice dowsers were able to follow an underground stream, flowing in a brick-lined culvert with absolutely no surface indications, for over 1km - they were astounded when the party ended up at a building site where the surface stream and its entry to the culvert were plain for all to see. A general theory of the mechanism of dowsing, which will permit scientists to incorporate it into scientific knowledge, is still lacking, but meanwhile it seems that many, perhaps a majority of cavers are willing to sit on the fence, and to have dowsing judged by its accuracy and practical value in the location of new caves, rather than by theories and opinions. Just two of the recently published scientific studies involving the location of caves by dowsing will be mentioned here (Mogila, 1985; Herbert, 1990; France, 1991a, 1991b). In 1581 the Italian Alessandro Guanini wrote that there were vast underground caverns dug out by the monks at Kiev, and said to be over 130km in total length. In the opening up of the tourist site at the Monastery of the Caves in Kiev, the Biolocation (i.e. dowsing) Group attached to North Ukraine Geology, an institution that prospects for ores and other resources, was invited to find some of these unknown passages. Mogila (1985) reported that the dowsers indicated 130 cavities. Of these, 73 were sites already known to the curators, but not previously known to the dowsers. A further 29 sites were unknown to the curators, but produced cavities on drilling. This was a total success rate of 78%. Malcolm Herbert (1990) described the South Wales Caving Club dowsing exercises at Pant Mawr and in the area between Waun Fignen Felin and Sinc-y-Giedd, which developed into part of the Greensites (i.e. detecting caves under featureless ground) Project. Stuart France (1991a; 1991b) has provided much more detail on this; of the battery of techniques investigated, many were prohibitively expensive or too slow, and resistivity has produced the best results; but dowsing did give a reaction in the correct general area and in the correct direction of the known passage - it is best to conclude that there is some correlation between underground anomalies and dowsing results, but much more confirmatory work needs to be done ("the jury is still out").

Review of the 1989 dowsing results

All of the 1989 dowsing traces referred to in the previous paper (Wilcock, 1989) have been gone over again, and found to be consistent and repeatable. The projected route which has provoked most discussion is the remarkably indirect southern route via Silverdale Barn, the Studfold spring line, and Dry Beck. Much of the route has peat bogs with no visible outcrops of rock, but geologists suggest that the basement beds form a raised "tongue" with Long Lane as its spine, overlain by limestone. Some discussants have said that the route could not possibly go that way because of the outcrop of basement beds in certain fields; however, it was always proposed that the cave, should it exist here, would be at the junction of the basement beds and the limestone, with basement beds forming the passage floor, as in White Scar Cave. The projecting tongue of basement beds would under these circumstances force the cave to follow a contouring route around the tongue under the prevailing hydraulic gradient to Brants Gill, and nothing which has been said has proved that this could not in fact be the case. Clearly water is forced SW, as is evident from the copious springs in the Studfold area; whether the passages are negotiable by cavers or divers is of course another matter.

New Cave Exploration Since 1989

Recent diving at Gingling Hole and the resulting cave survey has confirmed the general direction predicted by the 1989 dowsing, the prevailing direction being towards the northern end of Silverdale. Diving at Dub Cote also confirms the predicted route of outflow water from the general direction of Larch Tree Hole.

Further Dowsing Work (1992)

The following descriptions are a hypothesis which is entitled to stand until disproved. If correct, a further 4km of passage is revealed, forming the main Fountains Fell Master Cave heading NW from the northern end of Silverdale to the Dub Cote phreas, thus suggesting that the main route for the Fountains Fell water is from Silverdale under the flank of Penyghent, then via Dub Cote and Brackenbottom Water Supply to Douk Gill and finally to Brants Gill. On the illustrated map the dowsing traces are shown as thick black lines. There appear to be two large parallel passages, if the dowsing results are to be believed. It is now 40 years since it was first proved that the Fountains Fell water resurged at Douk Gill and Brants Gill. All the energetic explorations have resulted in sumps near resurgence level. Unfortunately, therefore, it is the cave divers to whom we must probably look for further exploration. However, there are several shakeholes over the predicted routes, which might provide high-level entries. It will not be an easy undertaking.
