Feature (archaeology)
Encyclopedia
Feature in archaeology and especially excavation has several different but allied meanings. A feature is a collection of one or more contexts
Archaeological context
In archaeology, not only the context of a discovery is a significant fact, but the formation of the context is as well. An archaeological context is an event in time which has been preserved in the archaeological record. The cutting of a pit or ditch in the past is a context, whilst the material...

Vertical direction
In astronomy, geography, geometry and related sciences and contexts, a direction passing by a given point is said to be vertical if it is locally aligned with the gradient of the gravity field, i.e., with the direction of the gravitational force at that point...

Horizontal plane
In geometry, physics, astronomy, geography, and related sciences, a plane is said to be horizontal at a given point if it is perpendicular to the gradient of the gravity field at that point— in other words, if apparent gravity makes a plumb bob hang perpendicular to the plane at that point.In...

Sequence (archaeological)
The archaeological sequence or sequence for short, on a specific archaeological site can be defined on two levels of rigour.# Normally it is adequate to equate it to archaeological record. However, the two terms are not exactly interchangeable...

, such as layers, dumps, or surfaces are not referred to as features. Examples of surfaces include yards, roads, and floors.

Features tend to have an intrusive characteristic or associated cuts

. This is not definitive as surfaces can be referred to as features of a building and free standing structures with no construction cut can still be features. Midden

s (dump deposits) are also referred to as features due to their discrete boundaries. This is seen in comparison to leveling dumps, which stretch out over a substantial portion of a site. The concept of a feature is, to a certain degree, fuzzy, as it will change depending on the scale of excavation.
