scientific studies designed to discover processes that produced and/or modified artifacts and sites.
a type of material remain that cannot be removed from a site such as roasting pits, fire hearths, house floors or post molds.
a network of uniformly spaced squares that divides a site into units; used to measure and record an object's position in space.
