Yuba Goldfields, California
 (JPG) (434,674 bytes) ( 1,415 x 1,101 )
The Yuba Goldfields are located along the lower Yuba River about 10 miles east of Marysville, California. They are a major gold mining dredge field that extends along the river about 13 km. The river and streams here were first worked during the gold rush by small-scale placer methods. Bucket-line dredging began in the district in 1903 and was perfected into one of the most efficient methods for mining placer gold. The district was dredged almost continuously from 1903 to 1968 and was the principal source of gold in California for some time. The estimated total output from dredging was estimated at 4.8 million ounces. More than a billion cubic yards of gold-bearing gravels were dredged. The extensive piles of gravel have become increasingly important as sources of aggregate. This simulated natural color ASTER image was acquired August 29, 2001, covers an area of 21.2 x 16.5 km, and is centered near 39.2 degrees north latitude, 121.5 degrees west longitude.
