NM 7139 1274 Work to assess, survey and record the submerged evidence for slate quarrying and related activities at Belnahua in the Firth of Lorn was undertaken 12 October 2015 – 9 September 2016.
The two slate quarries were abandoned during WW1. They flooded after pumping ceased and have since, apart from one unsuccessful attempt at salvage in the 1940s, been left untouched. Although some underwater photography of quarry features had been undertaken prior to 2015, no
archaeological survey had been carried out.
The archive assessment produced an archive of 550 digital files. Relevant material included terrestrial surveys and mapping, an equipment inventory of the similar Toberonochy quarry and an overview of the slate quarrying history in Scotland.
The snorkel and dive survey located, mapped and recorded a total of 31 archaeological features. Most have been identified and include slate bogeys, wall structures, pipes, rails, fire beaters, machinery and pottery. Three areas relating to different work processes were identified within
the quarries: slate extraction, slate processing and slate waste areas. Photographs were geotagged using a GPS buoy. Since the project was commissioned, the quarries have been added to the schedule of nationally important monuments (SM13216).
