The oldest human settlement in Central California is located in Scotts Valley, California, and was discovered in 1978.[1] Archaeological findings from 1983 and 1987 support dates as old as 9-12,000 years, based on carbon dates, geological context, and artifact styles, such as eccentrics (or crescents) and large leaf style projectile points.[2][3]
This ancient settlement (CA-SCR-177) was first recorded in 1978 and later tested in 1980 by Archaeological Research Management. A report was delivered to the Scotts Valley City Council in 1980.[4] The Council disregarded the report and the Mayor, Friend Stone directed the attempted destruction of the site. After appeals by the Santa Cruz Archaeological Society were ignored by the Council, the Society sued (Nov. 1981) to have the Cultural Resource Materials considered under CEQA (California Environmental Quality Act). In Nov. 1982, in an out- of-court settlement,[5] the City of Scotts Valley agreed to change their planning procedures to consider cultural resources more fully in the future, and to fund (via the Society) efforts to document and expand the archaeological sample in the damaged areas to see if the age and significance of the site as stated in the 1981 report were supported.[6]
The Santa Cruz Archaeological Society organized for Memorial Day weekend, 1983,[7] what would turn out to be the largest volunteer excavation crew ever assembled for such an occasion. This work supported the previous research and led the City of Scotts Valley to have to fund a large excavation in 1987 as the project development plans were changed.
These volunteer excavations produced artifacts and other data that supported the previous research; including a chert crescent tool[8] and a leaf-shaped chert biface that supported an estimated date of 7-10,000 YBP, and a metate feature, which is one of the oldest dated examples of ground-stone in California.[9]
Many scholars were involved in the analysis of the over 13,000 stone tools, artifacts and ecofacts from both the 1983 and 1987 excavations under the coordination of Dr. Robert Cartier. The final monograph was published by the Santa Cruz Archaeological Society and A.R.M.[10] There was a display at City Hall created by A.R.M. Artifacts that were discovered in both excavations were later curated at UC Santa Cruz.[11]
The monograph reported on the extensive analyses done that related both to the findings in time (back 12,000 years) and space (to previous archaeological findings in Western North America). A series of chapters, written by various scholars, includes careful examination of the history of what produced the excavation, how the volunteer excavation was carried out, and the analysis of the various data generated from both the 1983 and 1987 excavations.
The findings concluded that based on the thirty-seven radio carbon dates, the seventy-two obsidian hydration readings, the well-dated stratigraphic profile, and the diagnostic style of the artifacts that all data supported the 7 to 12,000-year-old antiquity of CA-SCR-177.[10]
Cartier notes in his concluding comments:
Archaeologist Gerrit Fenenga, in his chapter in the monograph, adds, "The Scotts Valley Site is clearly of great significance locally, regionally, statewide and in North America".[15]
