Presentation Transcript
slide1
Dendrochronological Reconstruction
  • Dates
    • Relative sequence
    • Absolute dates
    • Errors in archeological interpretation
  • Behavior
    • Construction habits
  • Environment
    • Climate in the past
slide2
Dendrochronology Dating
  • Does date of wood sample = construction date?
slide3

Archeological Interpretation of Dates

  • Outer date predates construction event
    • Collected dead tree
    • Collected a bunch of trees, stockpiled
    • Reuse a beam from old house
      • 14th century log used in 1929, Oraibi
    • Large sites versus distinct sites
  • Outer date postdates construction event
    • New log put in during repair
    • Problem or solution?
      • Could date repair sequences
slide4
Date Clustering Saves the Day
  • Given lots of dates, the date of construction event will be the best cluster of dates
    • Most frequent date
slide6
Date Clusters
  • Skewed beginning: slow development of site
  • Steep ending: fast abandonment
  • Early dates may be stockpiling, re-use
  • Late dates may be repair beams
  • Requires a lot of dates, replication
slide7
Cutting Date or Not?
  • Outermost ring was when tree died
  • Evidence of cutting date:
    • Bark, best but not common
    • Complete outer ring
    • Beetle galleries
    • Dark patina veneer
slide8
Non-cutting Dates
  • Some number of outer rings lost
    • Erosion
    • Shaping
    • Burning
  • What to do?
    • Estimate # of outer rings
    • Admit non-cutting and leave it
    • Rely on clustering
slide9
Behavioral Characteristics
  • Type of cutting devices
    • Fire
    • Stone axes
    • Metal axes
  • Repair schedules
  • Stockpiling, cooperation

SW Archeology Sequence
  • Chaco Anasazi: abandoned by 1130-1150
    • Start of a long period of drought

SW Archeology Sequence
  • Mesa Verde Anasazi: abandoned by 1280s
    • In period known as Great Drought

SW Archeology Sequence
  • Kayenta Anasazi: Betatakin, Keet Seel begun by 1250, abandoned by 1300
    • Perhaps affected by arroyo formation
