WLC site description

Part of the Clackmannan Group sites

Other designations: AGLV; CP (adjacent to Beecraigs Wood)

This site is located within the Beecraigs Country Park three km south of Linlithgow. The Hillhouse Limestone (Lower Limestone Formation) has been worked by both underground and surface methods. The 9 to 12 m thick massive and fossiliferous limestone dips to the west at 30–400 with consequent steep stoop and room workings, some of which have collapsed recently leading to subsidence in the overlying road. The limestone is overlain by a sill of basalt with columnar jointing — this is the type locality of the Hillhouse type of olivine-basalt in the 1928 MacGregor basalt classification.
