35. Pre-1906 Earthquake Chinatown Artifacts Found in Subway Construction
The Central Subway project, a line that would ultimately link Chinatown and South of Market in San Francisco, led to the discovery of what turned out to be 19th-century industrial sewing machines. They believed these sewing machines were used in the basement of a Chinatown factory that likely burned down or collapsed in the 1906 earthquake and ensuing fire. Sonoma State University was one of several archaeological consultants hired to assist with the excavation and analysis.
