**Abstract of Information Available**
Human remains representing, at least, two individuals have been identified. The 1,660 associated funerary objects are modified faunal bone, unmodified faunal bone, shell beads, modified obsidian, historics, unmodified shell, flaked stone debitage, petrified wood, groundstone, and modified stone tools. The individuals and associated funerary objects were removed from CA-SON-1082 in Petaluma, California in Sonoma County. Due to planned road widening at the site, Sonoma State University conducted a survey, drilled auger borings, and excavated two units in 1980. The resulting material has resided at Sonoma State University since that time. During Tribal consultation two individuals were identified associated with the work done in 1980. In 1982, additional items were collected during monitoring of a driveway construction at CA-SON-1082. Since 1982 the material from this monitoring has resided at Sonoma State University.
Human remains representing, at least, one individual has been identified. The 8,167 lots of associated funerary objects are modified obsidian, groundstone, unmodified shell, flaked stone tools, modified faunal bone, quartz crystals, daub, petrified wood, lithics, charmstones, unmodified stone, flaked stone debitage, modified shell, clay, soil, unmodified faunal bone, ash, float samples, lithics, historics. The individual and associated funerary objects were removed from CA-SON-977, CA-SON-978, CA-SON-979, and CA-SON-980 in Santa Rosa, California in Sonoma County. Due to planned construction of a holding pond, in 1977 Sonoma State University engaged in field testing at the sites within the construction area, CA-SON-977, CA-SON-978, CA-SON-979, CA-SON-980. Work done included surface survey, auger borings, and excavation at all four sites. In the catalog, remains from an individual are listed from CA-SON-978, but no further information was able to be located. Since 1977, the results of this work have been held at Sonoma State University. Later, items from CA-SON-979 were donated by Michael Joerger in 1979. Further circumstances of the acquisition are unknown. Since 1979 the cultural items have resided at Sonoma State University.
The 167 lots of associated funerary objects are flaked stone debitage, modified stone tools, ground stone tools, unmodified faunal bone, historic material.

Sonoma State University has determined that:
• The human remains described in this notice represent the physical remains of three individuals of Native American ancestry.
• The 10,042 objects described in this notice are reasonably believed to have been placed intentionally with or near individual human remains at the time of death or later as part of the death rite or ceremony.
