| Description: | Old quarry (now filled up), 0.8 km. south-west of Slateford, Midlothian. Sandstone being worked at the ?new? Redhall Quarry, Edinburgh, 13 August 1889. The sandstone, which is being worked for building stone, is overlain by about 12 feet (3.6 m.) of black shale and 20 feet (6 m.) of till or boulder clay. The row of boulders lies at the base of the till. The overburden of till above the shale and sandstone is abnormally thick in this part of the quarry due to the infilling of a glacial gouge formed during the Ice Age. This overburden, or ?tirr? as quarrymen call it, along with the shale would need to be removed before the sandstone could be worked. A split boulder, possibly split by the quarrymen using wedges; a wooden trestle and planking, a wheelbarrow and picks lie on the topmost bed of sandstone. A long upright crowbar stands against the shale overlying the sandstone. Redhall stone was used in a number of notable buildings in Edinburgh during the 19th century, including St. John?s Church, Princes Street and Film House, Lothian Road. The quarry had ceased working by 1895. The photographs were taken to illustrate the glacial gouge or ?washout? described by James Bennie in a paper which appeared in the Proceedings of the Royal Physical Society, Vol. X, p.392-396. |
