Description: | Stonegunn Quarry, 4.8 km. south-east of Thurso. Caithness. Method of levering the flagstones. The horizontal bed of rock is first split using chisels hammered in with a sledgehammer. It is then levered off the bedding plane with a crowbar. A quarryman in dress of the time (c.1910) is clearly seen. The rock is Devonian (Old Red Sandstone) Caithness Flagstones. After splitting each flag is taken away by means of crane and is subjected to preliminary squaring. |
