Tertiary Gravels of the Sierra Nevada also known as Professional Paper 73 by Waldemar Lindgren is probably one of the most important publications written on the Auriferous Gravel Channels in the Sierra Nevada of California. These ancient river channels were the majority source of the massive placer gold deposits that supplied the Mother lode.

The Tertiary Gravels of the Sierra Nevada of California
The peace of the wilderness was interrupted in 1849. An army of gold seekers invaded the mountains; at first they attacked the auriferous gravels of the present streams, but gradually the metal was traced to the old Tertiary river beds on the summits of the ridges and to the quartz veins, the primary source of all the gold in the Sierra Nevada.

California Gold Production Summary – Western Mining History
Lode mining of gold became important in the 1860's, and between 1884 and 1918 gold-quartz veins were the major source of California's gold production. Beginning in 1898 placer mining was rejuvenated when huge bucket dredges were introduced to work the auriferous gravels of the rivers flowing westward from the Sierra Nevada.

The Forest Hill Channel was 1,500 feet wide in much of the mine, and the average width of breasted gravel was 75 feet. A thickness of 2-14 feet of gravel was extracted and yielded an average $7.00/ton. Actual yields ranged from $3-$50/ton, but in one extraordinary 3,900-foot stretch it yielded $150.00 per running foot.
