Wyoming, often overshadowed by other gold-rich states, has a hidden history of gold discovery dating back two centuries. While not as well-known as California or Alaska, Wyoming holds its own when it comes to gold prospects. In this blog post, we'll delve into the intriguing history of gold prospecting in Wyoming and explore some of the state's rich mining and panning areas.
A Quiet Beginning: Spanish Discovery and Trapper Speculation
It is believed that the first recorded gold discovery in Wyoming occurred along the Sweetwater River in 1842. The area later became known as the Atlantic City-South Pass District. While some suggest that trappers had prospected the region and made the initial discoveries, the identity of the original discoverer remains a mystery. This was a time of ongoing hostilities with indigenous tribes, preventing the rapid influx of miners seen in other states.
The True Gold Rush Begins: Carissa Lode and Mining Districts
By the late 1860s to early 1870s, prospectors traced gold from the Sweetwater River upstream to the Carissa lode. This discovery marked Wyoming's first significant gold rush, leading to the creation of multiple mining districts. The Atlantic City-South Pass district, situated in Fremont County at the southern tip of the Wind River Mountain Range, emerged as the largest. Although precise production figures remain unknown, it is estimated that this district yielded up to 325,000 ounces of gold.
There aren’t a lot of places in Wyoming that will produce large gold nuggets, but they are out there if you know where to look!
Specimen-Grade Gold in South Pass Greenstone Belt
For those seeking specimen-grade gold samples, the South Pass greenstone belt, located at the southeastern margin of the Wind River Mountain Range, is a promising destination. This district encompasses gold-bearing veins, shear zones, and faults. Lander, situated approximately 23 miles south of this district, played a significant role in Wyoming's gold production.
Beyond South Pass: Other Mining Districts
While Wyoming may not be renowned for producing large gold nuggets, there are places where prospectors can find them with the right knowledge. Gold discoveries in various mountain ranges led to the establishment of additional mining districts, including the Douglas Creek District in Carbon and Albany counties, the Negro Hill District in Crook County, and the Snake River placers to the south of Yellowstone National Park.
Exploring Wyoming's Mining Heritage
The Wind River Mountain range, stretching from Sublette County to Fremont County, houses the Sweetwater mining district. Within this expansive district, gold camps like Atlantic City, Miners Delight, Lewiston, and South Pass flourished following Wyoming's gold rush. These camps owe their existence to the discovery of the Carissa lode, triggered by placers along the Sweetwater River.
Placer Mines and Douglas Creek District
The Douglas Creek District boasts placer mines along Douglas Creek and its tributaries. These placers span approximately fifteen miles in length and ten miles in width. A gold-quartz vein discovered in the Keystone Mine significantly contributed to the area's production. Notable tributaries in the district include Lake Creek, Muddy Creek, Spring Creek, Keystone Creek, and more.
The Decline and Shift to Copper
As the 20th century progressed, gold production declined in favor of copper mining. By 1959, total gold output reached around 82,000 ounces. Various factors, including the loss of veins in faults, accessibility challenges, increased mining interest in other states, and the financial struggles of mining companies, contributed to this decline.
A Glimpse into Wyoming's Gold Future
Despite the decline in gold production, Wyoming remains a promising destination for prospectors. Historical evidence suggests that the state has not exhausted its gold resources, and current sources are far from mined out. Wyoming's mineral history showcases gold discoveries across all its mountain ranges, both in lode and placer deposits, despite the relatively low attention given to the state's mining industry.
Prospectors with a sense of adventure and a willingness to explore the vast landscapes of Wyoming may yet uncover new golden treasures in this hidden gem of a state.
