A midden, also known as a kitchen midden, or a shell heap (when they contain a large number of shellfish remains), is a dump for domestic waste. 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.
