From Wikipedia, the free encyclopedia
The San Juan Ridge (39°22′40″N 121°01′33″W / 39.37778°N 121.02583°W) is a geographic feature extending approximately 24 miles (39 km) east-northeast between the South and Middle Yuba Rivers in the foothills of the northern Sierra Nevada.[1] The elevation is approximately 790 m (2,600 ft) above sea level.[2]
"The Ridge" was notable for hydraulic mining during the California gold rush,[3] the largest operation of its kind being run by North Bloomfield Mining and Gravel Company. French Corral was the first mining camp on The Ridge.[4] In the 1990s, research was conducted to renew gold mining efforts.[5]
