Description: Surveys and demonstrates modern archeological dating techniques and approaches. Illustrates the following dating techniques--tree ring, archeomagnetic, obsidian hydration, and radiocarbon--as well as the pottery typology and stratigraphy approaches used to determine the age of an archeological site. Depicts the practical applications of these approaches and techniques at prehistorical sites in the southwestern United States., Explores relative and absolute dating techniques archeologists use to date their finds. Shifts in the position of the magnetic north pole are recorded in the clay of ancient hearths. Radioactivity levels date organic matter. Even the relative position of one artifact to another can reveal a time relationship. Shows the processes by which the age of artifacts uncovered in an ancient Southwest American Indian pueblo site are determined by such methods as dendrochronology, archeomagnetic dating, obsidian hydration, and carbon 14 testing.
