Attempt to pinpoint a specific year or a range of years. Relative dates - involving unspecified segments of time, expressed as relationships or comparisons. Master sequence - a site with a deep stratigraphic profile that would permit the law of time-markers in the american southwest superposition to demonstrate the changing sequence of artifact types and styles. Pueblo san cristobal isolated a block of debris lacked sharp stratigraphic divisions excavated the block in 1 foot arbitrary levels. Method was revolutionary a fundamental excavation technique applied the law of superposition archaeologists use distinctive artifact forms to characterize and correlate strata between archaeological sites; pottery was a natural choice. 2000 potsherds grouped them into obvious types, then plotted their distribution according to depth below the surface. Type 1 - black designs on a white background.
