Monument record MHG5644 - Coroghon Mor, Canna

Alterations to the track approaching the 'prison' at Coroghon Mor (NG20NE 4) and construction of a British Telecom building there, exposed a number of layers of ash and shell midden separated by thick deposits of loam washed down from the adjacent slopes. Substantial quantities of decorated and undecorated low-fired Iron Age pottery had apparently come from the highest of these layers, on the N side of the track - below the lowest S-facing slopes of Compass Hill. Cleaning of the section and limited excavation of the ash deposits confirmed the origin of the pottery and indicated the remains of a burnt down structure, the timber and thatch roof of which had fallen and crushed a number of pots. After recording the pottery will be returned to the local collection at Canna House.
