The level of access referred to in this table is for guidance only and it is the visitors responsibility to ensure that they are able to access a site legally. All sites are either Sites of Special Scientific Interest (SSSI) or Regionally Important Geodiversity Sites (RIGS) and any hammering of faces, wilful destruction or damage of the site will not be tolerated. Specimens may be collected from loose material if required, but collecting should be kept to a minimum. Sites listed in columns 1 and 2 are not necessarily in heirarchical order. Where two sites are given they may simply be alternatives, or show different features within the same formation/member.
