Location and History
The Snelling district is in eastern Merced County along the Merced River between the towns of Snelling and Merced Falls. It is principally a dredging field. Some placer mining and hydraulic mining of the terrace deposits along the river were practiced during the gold rush. The town, named in 1851 for Charles Snelling, who operated a hotel and ranch here, was the governmental seat of Merced County from 1857 until 1872. Gold dredging began in 1907 and continued until 1919. There was dredging again from 1929 until 1942 and 1946 to 1952. The value of the total output of the district is unknown, but the dredges are estimated to have produced about $17 million.
Geology
The values were recovered from stream gravels and flood plain and terrace deposits in and adjacent to the Merced River. The gravels are loose with very little clay and range from 20 to 35 feet in depth. The dredged area is about nine miles long and 1/2 to 1 1/2 miles wide. Bedrock is slate in the east and volcanic ash in the west. The gold is fairly fine and about 890 in fineness. A small amount of platinum is present. Dredge recoveries ranged from 10 to 30 cents in gold per yard, with the average close to 10 cents.
