Q:
The Mazama ash has been dated at numerous locations in the western US to 6900 years old. This means that if an archaeologist finds the Mazama ash in a stratified context, he or she knows that everything above it is less than 6900 years old, and everything below it is more than 6900 years old. The Mazama ash is an example of a:
a. Colluvial sediment.
b. Soil horizon.

d. Sedimentary deposit that has been disturbed, resulting in reversed stratigraphy.
Q:

c. A stratum that is easily dated by the potassium-argon dating method.
d. A stratum marked by distinctive soil horizons.

a. arbitrary levels can potentially jumble together artifacts that come from different natural strata and thus different periods of time.
b. the depth of natural levels is determined by statistical sampling strategies, while arbitrary levels are chosen subjectively.
c. arbitrary levels follow the natural stratigraphy, which may not be able to distinguish between occupational surfaces.

a. archaeology destroys data as it is gathered; once a site is excavated it cannot be re-excavated.
b. federal legislation mandates abundant, accurate, and detailed field notes.
c. archaeology students generally learn field techniques from these notes.
d. none of the above; it is not essential because archaeologists can always go back and reconstruct the excavation later.
