Archaeology (Week 6)
-Must have a plan before excavating
-Excavation for horizontal and vertical control
-Open area excavation for better recognition of spatial patterning over large areas
oStratigraphy is recorded as excavation occurs and later constructed
oBest for single component sites that are relatively shallow
-Wheeler box grid provide a record of stratigraphy
oAllows layers to be traced and correlated across the site
-Step trenching is a way to estimate the site
-Cofferdam, Matagorda bay to be specific where archeologists dig through the wreck
-Stratigraphy
oArchaeological strata refer to the accumulation of natural and cultural debris in successive layers
oVertical/profile shows the accumulated layers creating a sequence
oSuperposition where what’s on top is the youngest and the bottom is the oldest constantly
oRed, green, purple, and yellow from oldest too youngest (1-4)
oOriginal horizontality where what’s on top is the youngest and the bottom is the oldest but there is
a slight bend in the centre outwards
oLateral continuity where what’s on top is the youngest and the bottom is the oldest but there is a v
shaped hole in the centre of the yellow and purple (3/4)
oCross cutting where what’s on top is the youngest and the bottom is the oldest but orange cuts
diagonal from 1 to 3 and there’s a total of 5 that differentially the age (5,3,2,1 and 4 diagonal from
-Recording evidence is investigation that carries through full excavation
oObservations and descriptions are usually recorded on journals
oRecording finds are documented in situ using photography where it was placed without being
tampered with
-Recording finds are described and recorded with maps
oLocations and height of deposition are noted
oWhen finds are removed, information is recorded on the containers
oPiece plotting is recording the vertical and horizontal location of each artifact, ecofact, and feature
-Recording evidence includes no cultural items
oSoil samples should be collected for later analyses
