Midden in the context of "Santa Cruz Province, Argentina"

A source text is a text (sometimes oral) from which information or ideas are derived. In translation, a source text is the original text that is to be translated into another language.

More generally, source material or symbolic sources are objects meant to communicate information, either publicly or privately, to some person, known or unknown. Typical symbolic sources include written documents such as letters, notes, receipts, ledgers, manuscripts, reports, or public signage, or graphic art, etc. Symbolic sources exclude, for example, bits of broken pottery or scraps of food excavated from a midden—and this regardless of how much information can be extracted from an ancient trash heap, or how little can be extracted from a written document.

Monuments (記念物, kinenbutsu) is a collective term used by the Japanese government's Law for the Protection of Cultural Properties to denote Cultural Properties of Japan as historic locations such as shell mounds, ancient tombs, sites of palaces, sites of forts or castles, monumental dwelling houses and other sites of high historical or scientific value; gardens, bridges, gorges, mountains, and other places of great scenic beauty; and natural features such as animals, plants, and geological or mineral formations of high scientific value.

A landfill is a site for the disposal of waste materials. It is the oldest and most common form of waste disposal, although the systematic burial of waste with daily, intermediate, and final covers only began in the 1940s. In the past, waste was simply left in piles or thrown into pits (known in archeology as middens).

Landfills take up a lot of land and pose environmental risks. Some landfill sites are used for waste management purposes, such as temporary storage, consolidation, and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction during an earthquake. Once full, the area over a landfill site may be reclaimed for other uses.
