Sites and Monument Record: Inveravon Shell Midden (SMR 173)
Mesolithic onwards, radio carbon dates ranging from 4820+-60 BC , 5435+-60 BC. and 5510+-60 BC were obtained following pipeline damage in 1983. The total EW length of the midden is approximated to be 120m.
The greater part lay on the west side, where the shell layer reached a maximum thickness of 3m. It appeared the shell had been deposited against a natural clay bank or low hillock, centred at NS 9519 7980 so that the shell layer thinned progressively to the east where it lay over beach sand. The midden is almost entirely composed of oyster shells, densely packed, interrupted occasionally by thin lenses of black ashy soil. Sandstone blocks were observed in one district, but of discontinuous horizon and on structural significance was attached to them.
A section of the midden was discovered by Mr Deans whilst improving the road in 1870.
