The stereographs in this collection contain photographs from between 1870 and 1871. They show hydraulic mining performed by the Gold Point Mining Company, Blue Point Gold Mine, Union Claim Mine, S.C.H.M. Company, and Rose Bar Claim at Sucker Flat, Yuba County, California.

These stereographs depict images from the Sucker Flat Mine, Yuba County, California. The first hydraulic mining in the California decade of the Gold Rush (re: 1849-1860) was done at the Blue Point Mine in Sucker Flat near the town of Smartsville (Yuba County), California. It was here that the first large scale primitive methods of washing auferious gravels began. Because of the primitiveness of the water hoses, nozzles, and engineering used, the easy gold played out. Later (1864-1871) hydraulic mining technology was perfected, allowing for stronger penetration into gravels (and the greater loss of soil to the rivers) and mining again brought people to Sucker Flat.
