Gold in Alder Gulch
Alder Gulch, located between Virginia City and Alder, is one of the most significant placer mining districts in the U.S., having produced over 2.5 million troy ounces of gold between 1863, and 1889. In total, miners recovered over $40 billion (today's prices) in gold from the gulch!
Almost as soon as prospectors discovered placer gold on Alder Gulch in 1863, the search was on for the mother lode. Gold-bearing quartz veins south of Virginia City – the most likely source of the placer gold – were heavily mined in the late 1800s, producing about 170,800 troy ounces of gold. Over time the gold eroded from the veins and was transported, concentrated, and preserved in the Alder Gulch gravels and channels.
The gold-bearing quartz veins originated from fluids generated from deep in the earth's crust over a billion years ago that had moved through planes of weakness in even older metamorphic rock where they were deposited. The extremely old metamorphic rock is widely exposed in the parts of the Tobacco Root Mountains, Ruby Range, and Gravelly Range that border Alder Gulch.

The devastated landscape of Alder Gulch is the result of gold dredging from 1899 to 1922. Dredge boats were floating sluice boxes designed to recover gold from the gravel buried deep under the gulch. Floating on ponds of their own making, the dredges literally turned the gulch inside out as they chewed their way through the gulch. Huge cast iron buckets deposited the gravel onto a conveyor belt that carried the gravel inside the dredge and onto a series of sluices and shakers. The gravel, minus the gold and soil was deposited behind the dredge boat onto the piles you see in the gulch today.
• Gneiss is a metamorphic rock exposed in areas around Alder Gulch. It started out as sedimentary and igneous rock, but over a billion years ago and at a depth of over 10 miles, extreme temperature and pressure transformed (metamorphosed) those rocks to gneiss.

• Much of the $126.7 million (today's prices) in gold recovered by the dredges on Alder Gulch in the early 20th century helped finance Harvard University in Cambridge, Massachusetts.
• Imagine Alder Gulch when five prospectors discovered gold here in May 1863. What do you think the gulch looked like then?

(This link is a detailed presentation on the history of gold mining in Alder Gulch - complete with many photographs and details.)
The miners organized a Mining District with regulations and officers: No one could file for more than 2 claims; Each claim was limited to 100 feet along the lode; A claim had to be worked at least 3 full days a week or it would be declared abandoned; No claim could use creek water more than 10 inches deep in their sluice boxes (Submitted on May 2, 2018, by Cosmos Mariner of Cape Canaveral, Florida.)
2. River of Gold.
In July 1863, hard rock gold was discovered nearly eight miles above Virginia City and the town of Summit soon grew. By fall of 1863, an estimated 10,000 people were living in Alder Gulch and the towns of Junction, Adobetown, Nevada City, Central City, Virginia City, Highland, Pine Grove, and Summit formed a nearly continuous settlement eleven miles long. Through the later 1860's placer claims were consolidated and hydraulicking began to replace shaft and drift placer operations. A complex and expensive system of dams and ditches brought water from the mountains to hydraulic mines near Nevada City. (Submitted on May 2, 2018, by Cosmos Mariner of Cape Canaveral, Florida.)
3. Bill Fairweather.
Bill Fairweather was one of Montana’s most intriguing characters. His find in Alder Gulch in 1863 could have set him up for life. Instead he died 12 years later, an alcoholic with nary a flake of gold to his name. “It (gold) just really didn’t mean much to Bill Fairweather,” said Ellen Baumler, interpretive historian at the Montana Historical Society. “He liked the excitement of the gold runs, but gold itself didn’t have any meaning.” Fairweather was known to throw nuggets in the street as he rode by, “letting the Chinese and kids scramble for it,” said Baumler. “He supposedly fed gold dust to his horse, Old Antelope. He would say if it’s good enough for me, it’s good enough for my horse, and he would put gold dust in the hay.” (Submitted on May 2, 2018, by Cosmos Mariner of Cape Canaveral, Florida.)
