 In May 1998, Greg & Marie were in the process of having an in-ground pool excavated on the property grounds, when contractors uncovered a 400- to 500-year-old Native American village or burial ground, likely inhabited by the Patwin tribe.The coroner and Native American Heritage Commission were contacted, and the anthropology department of UC Davis was called in to recover the unearthed artifacts.For six days, volunteers, UC Davis undergraduate students and professors, spent 240 hours on-site collecting materials and studying the dig.
