When I picked up the old photo in an Antique shop in Albany I was immediate struck by hpw the suspension bridge supporting a water pipe across a river could be the one across the American River to the Zantgraf mine built in 1899. But upon closer inspection, and studying a companion photo, this suspension bridge was at another site in California. My research indicates that the suspension bridge was built to deliver water to a 1930’s hydraulic mining operations on the east side of the South Fork of the Trinity river, just south of the confluence of the South Fork and main Trinity River in Salyer, CA.
