During building works in the end of the 20th century, two strange findings revealed something of the areas geology. In one area of the village high on the side of the hill and about 100 feet above the flat area of the village, excavations for 1m deep foundations of a house broke in to a pocket of sand and which was found to extend greater than 5m. The subsequent house had to be built on a raft on the sand. The sand was understood to have been examined by Exeter University (?) who considered it to have been a pocket pushed up by a glacier during the last ice age ! At similar time in the flat area of the village, excavations for foundations revealed large rounded and smooth stones which were put down the wide water course having been present at some time rather than the small river that flows through the village now.
