David A. Fredrickson Archaeological Collections Facility

The ASC’s Collection Facility is one of the largest such facilities in northern California. It contains more than 500 individual collections that are used for research and education. In 2004, we opened the new David A. Fredrickson Archaeological Collections Facility building. Although the building does not fully meet 36CFR79 standards (it has no climate control), it is alarmed, staffed, has a fire-suppression system, and is supported by an endowment of over $1,000,000 from curation fees. The facility consists of over 3,500 square feet of curation space and is currently accepting collections from sites in northern and central California.


The David A. Fredrickson Archaeological Collections Facility (ACF) at Sonoma State University houses and maintains Northern California prehistoric and historic-era archaeological collections and their supporting documentation as educational, scholarly, and heritage resources. At ACF collections are:

  • maintained in perpetuity in a stable environment
  • made available to students, scholars, and the general public for research and educational display, in accordance with ACF’s policies
  • considered a resource for the future

For collection and curation information, please contact Sandra Massey.

2013–2014 Summary

The David A. Fredrickson Archaeological Collections Facility (ACF) issued 20 accession numbers during the past year for projects from Lake, Mendocino, Marin, Napa, San Francisco, Sonoma, and Tuolumne counties.

Public service offerings by the ACF in the past year included hosting several school group tours of the facility as part of the ASC’s Interpretive Outreach Services (IOS). The ACF also provided materials and artifacts for a number of IOS presentations and displays both here at Sonoma State University and at off-campus locations.

Collections housed at the ASC are available for study or loan to qualified individuals and groups. The ACF received one inquiry from a researcher requesting access to shellfish remains found at historic-period Bay Area sites. The ACF was also visited by an individual who believed he may be a descendant of historic-period residents of a dwelling site excavated during ASC’s San Francisco–Oakland Bay Bridge West Approach project in San Francisco, and wanted to learn more about the research done during the course of the project.

The ACF had three student interns this year. In the fall term, Jeanne Sloane and Angela Turner were each assigned several collections to inventory. The collections were physically compared to the catalog on record, corrections made and entered into a spreadsheet, and the collections brought up to current curation standards. In this way, the student gains a preliminary knowledge of artifacts as well as a better understanding of collections management.

In the spring term Mark Castro created an interpretive display for the Navarro-by-the-Sea Center for Riparian and Estuarine Research, using artifacts found during construction monitoring at the Center. The display was installed at the Center in May 2014.
