Probabilistic Excavation
Stratified, Random, Random Interval
Judgmental/Haphazard Excavation
Areas of Interest Visible Features Remote Sensing Land Forms Soil Types Judgmental- knowledge and assumption Haphazard- random chance.
Datum Plane
An arbitrary horizontal plane across the surface of site, where vertical is measured from
Arbitrary Levels
Vertical units of equal length
Pro- fast and easy, ubiquitous sold
Con- Can mix stratigraphic units together.
Natural Level
Collecting all material within individual strata.
Pro- Don’t mix different depositions.
Con- Harder to follow, and stick with strata
Profile
Culture historians dig deep to get stratigraphy
Planview
Culture Recontructionists and processualists want horizontal space.
Problem with Profile vs Planview
Difficult to see both dimensions at once
Methods to maximize one over other
Excavation Blocks
Good horizontal coverage, lose all internal profile
Trenches
Exposes vertical strata, can’t see horizontal space distribution
Rice-Chex/ ice cube tray
Leave spaces between all square units
both vertical and horizontal views are discontinuous
Checker Board
Divide into grid, excavate every other unit
Pro- saves 50% of arch. Record, move less earth, repeatable
Con- Horizontal is discontinuous. Hard to stick to assigned units
Trench Block
4 trenches around a block to expose stratigraphy.
Pro- ultimate control of profile and planview of inner block
Con- difficult, assumption inner block is of value, sacrifice outer trench provenience
Expandotrench
Excavate trench in arbitrary levels, smaller blocks stepping out
Pro- gives stratigraphic control across horizontal
Con- Planview must be reconstructed in lab
Archaeological Context
Processes that occur after artifacts enter the ground. Mech and Chem.
Systematic/Behavioral Context
An artifact’s life history, what happen before deposit
Michael B. Schiffer
N-transforms- natural change
C-tranforms- cultural change
“absence of evidence is not necessarily evidence of absence”
Positive Evidence
finding artifact/ artifacts that support theory
Negative Evidence
not finding artifacts/ artifacts that don’t support theory
Why stuff may be missing from record
Not there
Looked in wrong place
Failed to recover
Material not preserved
Life History of Artifact
Procurement- how material was obtained
Manufacture- how material was formed
Use- how artifact was used
Recycle- artifact could be used for other task, or resharpen
Loss/Discard- human drops/loses/throws away artifact
Mechanical Movement
Streams, Landslides, Humans, Animals
Chemical Alteration
Chemical Decay of objects
Heat, Humidity, acidity, material
Preservation = M, C, D, S, T
Material (Perishable(Organic), Altered, Imperishable)
Climate- Temp, Hot=decay
precipitation= decay
Deposition- Rapid Burial= better preserve
Sediment- pH, Acid-mineral Base- Organic
Time- more= more decay
