Summary Excavations were carried out on two sites containing traces of iron ore processing, as part of the N-W Ethylene Pipeline Project, funded by Shell Chemicals UK Ltd. The excavations at Scabgill revealed a small part of an iron ore processing site apparently dating to the later medieval period or earlier. At nearby Boghall, a small furnace was excavated, which, while not itself datable, was also used in the processing of low grade, bog iron ores.
