Artifacts

One of many: Bud Light in the White’s Lane Woods (yesterday)

Wikipedia: A midden, (also kitchen midden or shell heap) is an old dump for domestic waste[1] which may consist of animal bone, human excrement, botanical material, vermin, shells, sherds, lithics (especially debitage), and other artifacts and ecofacts associated with past human occupation. The word is of Scandinavian via Middle English derivation, but is used by archaeologists worldwide to describe any kind of feature containing waste products relating to day-to-day human life. They may be convenient, single-use pits created by nomadic groups or long-term, designated dumps used by sedentary communities that accumulate over several generations.

These features, therefore, provide a useful resource for archaeologists who wish to study the diet and habits of past societies.
