The Process
![Page 5: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/5.jpg)
Setting Up a Unit
2 meters
2 m
eter
s
Standard archaeological units are 2 meters by 2 meters. These units lie within a grid established from a fixed starting point.
![Page 6: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/6.jpg)
Who was Pythagoras?
Archaeologists use the Pythagorean theorem to find the hypotenuse of a right triangle. If all the measurements are correct, the units are square.
a2 + b2 =c2
![Page 7: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/7.jpg)
Dig, Dig, Dig!Once the unit is laid out, ground breaking begins as you dig through the plow zone. The pile of dirt and sod that is created is known as the back dirt pile. It is always in the wrong place!
![Page 8: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/8.jpg)
Skimming Off the Plow Zone
The plow zone is a 25 cm layer (approximately) that is disturbed by the plow. Artifacts found in this area indicate the possibility of a site but not an exact location.
Archaeologists need to get below the plow zone to find in situ artifacts.
![Page 9: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/9.jpg)
Putting the Trowel to Work
The trowel helps level the unit and makes any stains more pronounced. Make sure you trowel in the same direction to avoid trowel lines.
![Page 10: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/10.jpg)
Looking for Stains
A stain is a color variation in the soil. Stains give archaeologists an indication of past human activity.
Do you see the stain?
![Page 11: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/11.jpg)
Setting the Datum
The datum is the point archaeologists use to measure from. They measure down from the datum line which has a level attached. This keeps each level an equal distance below the datum point.
![Page 12: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/12.jpg)
Layer by layer
A layer of 5 cm of soil is removed from a feature. This is called a level. Levels are identified by a sequential level number and the measurement below datum (cmbd).
Anything found in the layer is placed in an artifact bag and labeled.
![Page 13: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/13.jpg)
The Matrix
Matrix is a sample of soil from the level of a feature. The matrix is floated to collect very small fragments like charcoal, pollen, or seeds.
What’s missing from my label?
![Page 14: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/14.jpg)

Screening
Soil not collected in a matrix is screened at the site. Artifacts found in this process are also bagged and labeled.
![Page 16: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/16.jpg)
Using the Bamboo
A bamboo pick is used to remove soil from around an artifact so it can be removed without damage. It is also used to create a pedestal under the
object so the entire item can be exposed without removing it. When several items are exposed in a single layer, an archaeologist can use the
context to draw conclusions about past human activities.
![Page 17: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/17.jpg)
Painting – sort of!
A paint brush is used to clear loose dirt from off of or around an artifact. This prevents damage to the artifacts.
![Page 18: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/18.jpg)
Mapping the Feature
Once the level has been completed a map must be drawn of the feature. Careful measurements are taken and any artifacts that extend beyond the level, large artifacts in situ, additional stains and rodent disturbances are placed accurately on the map.
![Page 19: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/19.jpg)
Paperwork Every level has an Excavation Level Form. The excavator indicates the site, feature, half, level, cmbd, methods used for excavation, screening, artifacts found and comments about the level.
Acquisition numbers at the top are used to label matrix and artifact bags.
![Page 20: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/20.jpg)
Field Journals
An archaeologist keeps a field journal. She records daily what has been done, how it was done, what was found and any other observations about the site.
![Page 21: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/21.jpg)
What happens to the artifacts?
Artifacts are placed in resealable bags. The acquisition number and provenience information are written directly on the bag along with information or instructions about the artifact. Very small, fragile artifacts like bone or shell may be placed in film canisters and large chunks of charcoal wrapped in foil for carbon dating purposes.
![Page 22: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/22.jpg)
Finishing Touches
The Munsell book is consulted to find the soil color. The soil color is indicated on both the map and the Excavation Form.
A photo is taken as a second record of the finished level.
![Page 23: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/23.jpg)
When the paperwork is finished, the feature mapped and the photo taken, the archaeologist tackles the next level. If sterile soil (soil outside the stain area) has been reached, the archaeologist goes back to the plow zone.
![Page 24: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/24.jpg)

The End…
…really it’s only the beginning!
![Page 28: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/28.jpg)
Meanwhile…back at the lab
All the matrix samples are dried and wait to be floated.
![Page 29: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/29.jpg)
Matrix samples are floated in water and poured through screens. Soil is washed away so that only artifacts, lithics and organic materials remain.
Looking for the little bitty treasures
![Page 30: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/30.jpg)
Everything collected in the screens is placed in cloth and set aside to dry.
![Page 31: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/31.jpg)
Organic matter from the matrix samples is analyzed and classified.
![Page 32: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/32.jpg)
Artifacts are sorted by type, carefully washed and set out to dry before being catalogued and stored.
![Page 33: Archaeology for Teachers Field School 2005 Patty Finger June 2005](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d035503460f949d6be6/html5/thumbnails/33.jpg)
The Final Stage
When everything has been sorted, classified, counted and a report written the artifacts are rebagged, boxed and stored until they are needed to tell a story of the people from the past.
