Arch. MIDTERM #1 Flashcards
challenges of archaeological preservation (4) (PNGH)
1) processes affect remains
2) needs to be put back together (like a puzzle)
3) Geological and environmental factors
4) human activity
what are examples of geologic and environmental factors and are they intentional or unintentional?
earthquakes, rain, erosion, flooding, dry etc.
unintentioanal
what are some challenges when geologic & environmental factors affect preservation?
1) organic materials can decay
2) artifacts can get washed away
what are some examples of human activity affecting preservation? (PFHL) (4)
unintentional
1) people leave or die
2) farming (plows over archaeological sites)
3) human settlement
4) looting (intentional)
identifying and mapping physical remains of human activity
survey (recovery method)
ways to perform survey (2) (WT)
1) walk around grounds
2) talking to people in the area
what are some challenges of survey (2) (tv)
1) terrain
2) vegitation (covered by dense foliage with insects)
any loci of past human activity
site
culturally or geographically defined cluster of sites
region
survey techniques (2) (GR)
1) GPS
2) Remote Sensings
types of remote sensings (survey technique) (2) (AL)
1) aerial photography (planes)
2) Lidar (light detection and ranging)
types of lidar (2) (A3)
1) aerial laser survey
2) 3D topographical map
Example of lidar
Caracol, Belize (4 days of lidar vs. 25 yrs of foot survey)
what is an advantage of survey?
non-destructive
what can survey reveal? (2) (IS)
1) identify relationships b/t sites and b/t sites and landscape
2) surface artifacts
exposure of remains via controlled digging
excavation
what is the goal of controlled digging?
to reconstruct everything and see how they fit together in space
how are sites created?
through STRATA
layers represent activities and deposit (cultural & natural) from different time periods
STRATA
sequence of STRATA built up in layers
stratigraphy
in an undisturbed stratigraphic sequence each layer (STRATA) is younger than the layer beneath
Law of superposition
are the younger strata on top or bottom?
top
problems with the law of superposition (2) (WM)
1) wall can be built on top of older strata
2) making sense of what you’re digging during excavation is most challenging
types of controlled excavation
1) grids (horizontal)
2) datum points (verticle)
