Where the land drops away toward the beach, a section of eroding earth reveals a dense band of limpet shells, roughly four metres long and packed into a layer of grey-dark brown sand. This is a midden, the archaeological term for a refuse heap left by people who ate shellfish, lit fires, and apparently heated stones, possibly for cooking, close to the shoreline. It is not a monument anyone built; it is what got left behind.

The deposit sits about a metre below the current field surface and roughly sixty centimetres above the cobbles and boulders of the present beach, which suggests the coastline and ground levels here have shifted considerably since people were gathering limpets at this spot. Mixed in among the shells are fragments of charcoal and stones that show signs of heat fracturing, a pattern consistent with the use of fire-heated rocks to boil water or prepare food directly on the shore. The midden lies just four metres north of a separate burial mound, itself exposed in the same eroding section of land, hinting that this small strip of coastal edge preserves more than one episode of early activity in the same tight locality. Whether the midden and the burial are connected in time or merely neighbours by chance, the notes do not say.
