This volume examines an almost purely lithic record known in the Puget Sound region as the Olcott Complex. Only loosely described off and on since the early 1960s by a series of researchers, none of whom used the same analytical approach, the Olcott record has never been systematically analyzed until now. As a result, this book fills in enormous gaps in our knowledge regarding the age, mode of subsistence, and adaptive strategy of the Olcott Complex. Chatters and colleagues describe the intensive excavation of three Olcott sites that were threatened by highway construction. The book concludes by pulling those findings together to place the Olcott Complex into its proper place in regional prehistory. An exemplary model of how to conduct archaeological research, the volume demonstrates how important research issues can be addressed in a cultural resource management context.
