Manuscript, typescript and traditional printed material created as part of the interdisciplinary Layers in the Landscape project, which applied the concept of deep mapping to the submerged landscape of Cardigan Bay, and in particular the submerged forest at Borth. The papers relate especially to the theoretical side of the project (notably the geomythology of Cardigan Bay and the relationship between poetry and archaeology in the 'King of the Sea Trees' poem), as well as the 'Borth's lost legends' exhibition at Borth Station Museum.
