All historic material stored at the Umatilla Chemical Depot is being moved to the Heritage Station Museum in Pendleton, according to the Umatilla County Historical Society.
About 2,000 photos, videos, documents, computer discs and historic objects are planned to be permanently preserved at the museum.
The depot operated from 1941 to 2012. The last mission of the depot, destroying 220,604 munitions and containers holding 3,717 tons of nerve and blister chemical weapons agents, was completed in October 2012.
Volunteers are needed to sort and organize historic material at the depot for its transfer. The first work session is July 31. Call 541-276-0012 for more information.
