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 $961,000 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.

2012–2013 Summary

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

One researcher who was not able to visit the facility in person was provided with digital photographs of artifacts from the collection that she wished to study. Two loans of collections and related documents were granted for research.

In addition to visiting researchers, the ACF was visited by a family descended from historic-period residents of a dwelling site excavated during ASC’s Cypress Freeway Project in West Oakland. The visiting group asked to view artifacts from the collection as a way to explore their family’s history.

The ACF had three student interns this year. Camilla Rockefeller in the fall term, and Kyle Runzel and Clare Burns in the spring term, 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. Diego Rocha continued a paid internship which he started in Spring 2012, inventorying collections from the Bureau of Land Management.
