| Description: | Hook Quarry, West Hoathly. Looking NW. Quarry in Ardingly Sandstone for building stone. The top 6 - 10 ft. of the Ardingly Sandstone is quarried from beneath a thin capping of Grinstead Clay (1 - 2 ft. yellow-brown clay visible below fence). Two good sets of joints in the sandstone (almost at right-angles to one another) have been accentuated by cambering and greatly facilitate the working. Wedges driven in along selected bedding planes suffice to free large cuboidal blocks. These are trimmed and sawn to the required shape and size and when used are laid with their bedding planes horizontal to counteract frost action (if laid vertical with a bedding plane facing outwards successive layers are flaked off by frosts). See also A10241 and A10247. |
