Collections Facility

The David A. Fredrickson Archaeological Collections Facility (ACF) is one of the largest such facilities in northern California. It contains more than 2500 individual collections that are used for research and education. Although the ACF building does not fully meet 36 CFR 79 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.
