Earth Ovens

Earth Ovens

A variety of terminology is being applied by archaeologists to a diversity of scoop features in New Zealand Maori archaeological sites. 
These features are usually interpreted as indicating cooking in earth ovens. 
Some greater degree of consistency is needed if the terminology is to be more rigorous. 

From Law G. 2008 “Hangi, Hangi Pits, Hangi Scoops, Umu, Scoops, Fire Scoops, Hearths, Scoop Hearths - Sorting Out What We Are Talking About” Archaeology in New Zealand 51(2): 95-105.

An Archaeological Terminology

Ovenstone – Stone in an archaeological context which suggests it was used or was intended for use in an oven – through size / shape selection, evidence of being fire affected, surface addition of charcoal.

Fire affected ovenstone – Fire broken or otherwise heat affected

Oven rakeout – Mixed charcoal and ovenstone, which may include shell and bone midden.

A descriptive typology:

Earth oven* | Scoop with ovenstones in place, with or without a fire affected base.

Inferred earth oven | Scoop without ovenstones, with or without a fire affected base, adjacent evidence of cooking including ovenstones (oven rakeout).

Scoop hearth / possible earth oven |Scoop without ovenstones, with a fire affected base or ash fill, with adjacent evidence of cooking in midden but not including ovenstones.

Scoop / possible earth oven |Scoop without stones, without a fire affected base or ash fill, with adjacent evidence of cooking in midden but not including ovenstones.

Scoop hearth| Scoop without stones, with a heat affected base or ash fill, but no adjacent evidence of cooking, or ovenstones.

Scoop |Earth oven or hearth like scoop, without other evidence.

Describe – it is not necessarily evidence for the local presence of earth ovens. | Fire affected stones, with or without charcoal / midden, no scoops.

• Using ‘earth oven’ as a term runs somewhat against the objective of a descriptive classification, but at this end of the classification the function is also clear.
