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.
