Abstract

Two sites from the Late Holocene period, the Fryingpan and Berkeley Rockshelters, are analyzed using an evolutionary archaeology model to test hypotheses about site-type expectations. Under the existing theoretical model, rockshelter sites on the slopes of Mount Rainier were used for a more limited activity set than some open-air sites. Rockshelter sites are thought to be places of short-term occupancy consistent with hunting and/or overnight residence activities. Large open-air sites with relatively dense and materially diverse lithic artifacts are thought to be longer-term residential base camps. Technological and functional paradigmatic lithic classifications are used to measure how rockshelter and larger open-air sites vary. The analysis is reduced further to focus on how the two rockshelter sites vary independent to each other, compared to the open-air Sunrise Ridge Borrow Pit site. Non-random associations of data frequencies across technological variables exhibited by the lithic assemblages determined that rockshelter lithic assemblages are representative of a truncated range of variability compared to open-air site assemblages.
