GLA 53: Charmwood Farm, Potential LIGS

GLA 53: Charmwood Farm, Potential LIGS
London Borough of Bromley, TQ 4616 6244
Ownership: GK Deniss Farms. Permission to visit from owner.

In a small wood midway between Little Molloms Wood and Charmwood Farm, there are a series of associated depressions and a half-filled open cast chalk quarry. The entrance arch is 1.5 m by 1.5 m. A steep descent follows into a chamber 4.5 m high. A short (9 m) blind tunnel leads off on the right and there are two connections, about 3m long, on the left to a parallel tunnel which once had its own entrance. The two parallel tunnels are each about 25 m long. In 1992 the Kent Underground Research Group dug a deep exploratory trench but only found loose chalk rubble, probably part of a roof collapse. The site is gated by a metal grille. As most of the surface exposures of chalk in the London area are in Seaford Chalk, this is the likely horizon here although this has not been confirmed.
