In the 19th century, California recorded a gold rush. After the first discovery of gold at the Sutter’s Mill in Coloma, thousands of people flocked to the state in search of gold. This period was known as the California Gold Rush. Finding a massive gold piece was one of the significant ways to make a fortune overnight at the time, and many people found it in the form of gold nuggets.

A gold nugget is a natural, shapeless piece of native gold discovered by placer mining (the process of separating heavy minerals like gold from sand) or by exploring sites of previous mining operations. People melt this into smaller fragments and gold dust, and it is highly valuable. Gold is measured in troy weight, which is a system of units of mass developed in England mainly used by those in the precious metals industry.

The largest gold nugget ever found weighed 195 troy pounds and was discovered at Carson Hill, California, in 1854.

Where Is Carson Hill Located on a Map?

Although it is now a ghost town located in Calaveras County, CA, Carson Hill was once a productive gold mining site in the state during the California Gold Rush of the 19th century.

The town is named after Sergeant James Carson, a member of Colonel Jonathan Steverson’s Regiment of First New York Volunteers. Carson made his way through Weber Creek and joined a gold mining party,. The party split at Angels Creek, and Carson headed south in search of gold. 

The group panned for gold at a small tributary of the Stanislaus River, where they finally found gold in 1848. This portion of the river was given the name Carson Creek. After the discovery, people flooded the area to dig up their own fortune and make a name for themselves. The area became known as Carson Hill after James Carson, and it holds the record of producing the largest gold nugget ever discovered in California.

How Was the Largest Gold Nugget in California Discovered? 

On November 29, 1854, five miners were digging for gold at the Morgan Mine in Carson Hill. While digging, one of the miners named Perkins discovered a 195-troy-pound gold nugget. The piece of gold he found was the largest in the world at that time and the largest found in California to date. Originally, the men intended to transport the gold nugget to New York for sale, but they sold it on the way to a New Orleans man for $40,000.

The Impact of the Discovery

The California Gold Rush had a profound impact on the state and the country as a whole. It brought a tremendous amount of wealth, and it helped shape California into the diverse and prosperous state it is today. 

The Carson Hill gold nugget is remembered as one of the most famous and valuable gold nuggets ever discovered in California. Though the whereabouts of the gold nugget is unknown, it made the list of the most popular nuggets ever discovered during the California Gold Rush. 

Many more miners and everyday people in search of gold flocked to Carson Hill to make their fortune after the gold nugget was discovered. It remains a symbol of the wealth and prosperity that the gold rush brought to the state.

Other Gold Nuggets Found in California

Apart from the 195-troy-pound Carson Hill gold nugget, there were other remarkable gold nugget discoveries in California during and after the gold rush. Most of these nuggets were discovered during the gold rush. Their discovery during different periods of the gold rush contributed to the influx of people rushing to dig for gold in the state.

The Monumental Gold Nugget

The Monumental gold nugget was discovered in 1869 at the Sierra Buttes Mine in Sierra County. The nugget weighed 103 pounds. The gold nugget was later broken down into chunks and gold dust. However, a crafted replica is on display at the Kentucky Mine Museum.  

The Magalia Nugget

In 1859, miners found a gold nugget (Dogtown nugget) in Magalia, California. It weighed 54 troy pounds. They celebrated the massive discovery and melted the gold nugget. However, the Paradise Chamber of Commerce and the Division of Mines and Geology own replicas of it. The Magalia people still hold a special annual celebration of discovery to this day.

A 50-Pound Nugget From Tuolumne County 

In 1851, one man known simply as Mr. Strain found a 50-pound slab nugget. He discovered the nugget near Knapp’s Ranch, Tuolumne County. It had a shape similar to a quartz slab, with a length of about 14 inches. It was four inches wide on one end and nine inches wide on the other end. The value of the gold slab was about $8,500 after he crushed and melted it. 

Gold in El Dorado

Miners discovered a crystalline gold piece from the grit mine near Spanish Dry Diggings, El Dorado County, in 1878. The nugget weighed more than 12.6 troy pounds, making it one of the biggest gold nuggets ever discovered in California. They sold the nugget to a Mr. Fricot, who lived in Grass Valley. The buyer never melted the gold piece. Instead, he sent it to Paris Exposition in 1878. It is currently on display at the California Mining and Minerals Museum in Mariposa County, where someone nearly stole it in 2012.

The Mojave Nugget

The Mojave nugget was found in the Stringer district near Randsburg, California, in 1977. A man known as Ty Paulsen discovered this nugget using a metal detector. It weighed about 12 troy pounds. 

Margie and Robert Petersen purchased the nugget and later donated it to the National History Museum of Los Angeles County. Based on 2022 estimates, the Mojave nugget would be worth approximately $270,000.

California has a long history of gold discovery, and the discovery of the largest gold nugget helped in the development of the state and the country’s economy. Today, gold mining continues in California. But it is at a smaller scale in comparison to the California Gold Rush. Still, mining activities generate revenue for the state.
