Gold prospection is old and wherever the gold was found in the state of Indiana, it was always associated with glacial drift. It was seldom found along the larger streams, but gold was found in the sands and gravels of the small streams which skirted the southern border of the drift and the area of the terminal moraine. The counties in which gold was discovered in noticeable quantities are Brown, Jennings, Morgan, Franklin, Northington and Warren. Gold was discovered in Morgan county as early as 1837.
In 1850, miners returning from the California Gold mines prospected the black sands of brown and Morgan Counties. The gold occurred in exceedingly fine grains and scales; the loss in washing was high. The statement was made that glacial drift, which was gold bearing, covered thousands of square miles and ranges from 10 to 500 feet deep. According to the first annual report of the State Geologist issued in 1869, gold was found in Franklin County on Sein Creek, but in such small quantities that it took a pailfull of sand and gravel to yield from two to three particles, usually scales and never larger than a grain of wheat. Mention is made of the finding of gold in Bean Blossom Creek. The fineness was twenty-four carats, which was attributed to the glacial action.
The reports for the following years stated that gold was found in black sand in the bed of the Muscatatuck Creek. In Northinggton County the drift had a depth of 100 to 150 feet and covered practically the entire area. Gold was reported in 1873 at Mooresville on a small creek. The sands and gravels were claimed to have yielded 25 to 190 colors to a pan. Silver mines were mentioned in the mining journals about 1888, as being worked in Dubois County, and the run of a local smelter on 750 kilos of ore reported 58 oz/t of silver and 4 oz/t of gold.

A glacier like this once covered Indiana to a depth of over two miles.
This glacier melted away only 12,000 years ago bringing with it gold and precious stones from Canada.
