Cormongers Lane

Cockley Works. Fullers Earth Works. Side trails on the mine. Large pits were worked here for over 100 years into the 1980s but the plant was stripped out in 1981 and finally demolished in 1988. The pits were then used for land filling which was completed in 1993 and the site landscaped.

Fullers Wood Lane

Green Hut. At east corner of junction of Fullers Wood Laneand the A25. The hut contains an electrical transformer but it was discovered in 1982 that it was the site of vestiges of underground workings. Only a small proportion of fuller's earth was ever mined underground in east Surrey but from time to time underground galleries have been uncovered by later working. A more spectacular demonstration of underground workings was a nearby collapse of the A25 in 1962,

RedhillSandCaves

In a large quarry half a mile east of Redhill Station. It is a very substantial hole in the ground, with a sloping entrance for lorries and earth moving equipment at the eastern end. It is over 200 ft. deep. The overburden is 100 ft. of Folkestone Bed sand, which is compact but decomposes into loose sand when disturbed. Beneath this is a thin band of stone, less than a foot thick. Underneath this is an unknown depth of Fullers Earth, and this is the main objective of the quarrying operation. There is a large opening halfway down the north face of the quarry and subsequent exploration showed it to be natural and formed by a very active stream. A pipe runs from the lip to the floor of the quarry to ump out a lake at the bottom and the cave is close to this. An ironstone horizon forms the floor of the cave.  The entrance to the cave is of double-decker bus size being some 15 ft. wide and 20 ft. high. The roof is a natural arch of sandstone. The passage is never less than walking height and continued round a few shallow meanders until it closes down suddenly into a wet crawl some 12 inches high.  The stream emerges from the crawl. The geomorphology of the cave can best be described as dynamic. It is visibly changing shape. The stream exits the cave and flows a short distance along a gulley, then over the edge of the ironstone band which is undercut, down a 2m. waterfall and then finds its way down to the bottom of the quarry, where it forms a greenish-hued lake. This lake threatened to cover the working surface of Fullers' Earth and an elaborate pipe system was in operation to take water out of the lake and all the way backing to the surface, for eventual discharge into the stream. The volume of water was particularly impressive And water also oozes out of the top of the ironstone band in several other places and there are several dry mini-caves in the vicinity. There is a low arch at the foot of the sandstone cliff some 150 metres distant. . This leads to another wide chamber. The floor at the lowest point is covered with a static pool of unknown depth. There is then a second standing height chamber of the same dimensions, ending at a blank wall dipping into the pool. Following winter rains the whole area turned into a quicksand, with no sign of any caves.
