Where do we dig?

We decide to excavate places that the survey tells us have more potential and where others have dug in the past. Your question helps you decide where to dig. Where ever you find relevant remains on the surface will direct you to where you want to go.

Excavation Procedure

Make a map, Establish a grid system, Determine your sample, Dig, Record your findings

Stratigraphy

a site's physical structure produced by the deposition of geological and/or cultural sediments into layers, or strata. Natural levels of soil.

Law of Superposition

the geological principle that in any pile of sedimentary rocks that have not been disturbed by folding or overturning, each bed is older than the layers above and younger than the layers below; also known as Steno's law.

Artificial vs Natural levels

natural breaks in the soil, artificial is picking 5 cms and digging that far down.

Provenience

an artifact's location relative to a system of spatial data collection, x, y, z, axis

Horizontal Excavation

Open up a very wide area to one particular level: may be looking for big things, mostly in one time period. What was going on at this entire site at one point in time.

Vertical Excavation

Narrower/smaller area to find the changes over time. How did technology change over time?

Water-screening

a sieving process in which deposit is placed on a screen and the matrix washed away with hoses; essential where artifacts are expected to be small and/or difficult soil (clay)

Flotation

carbonized remains, dirt sinks to the bottom and carbonized things will float to the surface.

Backfilling

refill the units once we are done excavating
