Detail from Brass Seal West side of Capitol:
Miner and Mercury Flask
Mining left a lasting legacy from the Sierra to the Sea
Champion Mine(had 4 mercury retorting sheds)Circa 1890
The mine tailings were discharged directly into Deer Creek, outside of Nevada City, CA
More than 96% of the total mercury loading to the Bay-Delta comes from the streams and rivers of the Sierra Nevada and the Inner Coast Range
(Wood et al., 2010).
