This paper presents a study of the Tarlton site, CA-SMA-248, as it relates to its neighboring deposits -- the Hiller Mound and University Village. The Tarlton site is a rich deposit on the bayshore of Menlo Park in close spatial proximity to the two other archeological sites. Radiometric dates are used to show the temporal relationships between the deposits which lead to tentative conclusions and further research directions about the Tarlton site.
