alignment

An alignment in archaeology is a co-linear arrangement of features or structures with external landmarks, in archaeoastronomy the term may refer to an alignment with an astronomically significant point or axis. "Alignment" may also refer to circumstantial or secondary type of evidence used to infer archaeological association of archeological features, such as postholes, by virtue of their physical relationships rather than stratigraphic ones. Types Large scale alignments The alignment of features on a site within or across several archaeological phases many times is an indication of a larger topology to the formation of features relating to activity in the archaeological record. Structures buildings and liner features such as ditches can all have common alignments that relate to a feature that is not exposed during excavation or is off-site. An example would be that a road has biased the alignment of features some way back from the actual road side. Another example will be contours or water courses which may be buried or obscure.
