01
Front

What is an excavation unit?

Back

A defined area chosen for investigation, often a square or rectangle laid out on a site grid.

02
Front

How does a context differ from an excavation unit?

Back

An excavation unit is a spatial division; a context is a distinct deposit, surface, cut, or built element recorded and interpreted separately.

03
Front

What should guide excavation-unit placement?

Back

Unit placement should test a clear research question and account for known evidence, topography, soil conditions, site boundaries, and areas to leave undisturbed.

04
Front

Why establish a site grid and datum before digging?

Back

A site grid tied to a permanent or relocatable datum, with consistent horizontal and vertical control, lets observations from separate units be compared and connected.

05
Front

How should excavators respond to a soil change?

Back

Observe and record soil properties and boundaries before interpreting them; not every change marks a distinct archaeological event.

06
Front

What is an archaeological feature?

Back

A non-portable or spatially defined archaeological element, such as a hearth, pit, posthole, wall, floor, or ditch.

07
Front

What is the difference between a pit’s cut and fill?

Back

The cut records the act of digging; the fill records material deposited afterward. They are different contexts.

08
Front

What sequence is implied by a feature cut into a layer?

Back

A feature cut into an older layer must postdate that layer; the feature’s fill must postdate the cut.

09
Front

Does deeper always mean older?

Back

No. Stratigraphic relationships provide relative sequence, not calendar dates, and disturbances or redeposition can disrupt the relationship between depth and age.

10
Front

How should distinguishable deposits be excavated?

Back

Excavate according to their boundaries and relationships rather than removing a uniform thickness through unrelated layers.

11
Front

What are arbitrary levels, and what do they represent?

Back

They are measured increments used as a control when internal boundaries cannot be reliably seen; they do not necessarily represent separate ancient events.

12
Front

Why keep spoil from different contexts separate?

Back

Keep spoil from separate contexts apart so finds retain their provenience.
