Rioville Nevada – Colorado Steamship Landing

Founded in 1865, Rioville, Nevada was founded by Daniel Bonelli at the confluence of the Virgin River and the Colorado River. Bonelli was a Mormon settler who was sent to the area by Brigham Young. The town is long since drowned in the rising waters of Lake Mead.

Originally known as Junction City, the small crossing of Stone’s ferry was purchase by Bonelli in 1870. Stone’s ferry was renamed Bonelli’s Ferry for its new owner, and the ferry crossing was moved to Junction City which was about two miles down river. In 1871, the site was abandoned by its settlers.

In 1880, a second wave of settlers arrived and the town was renamed to Rioville. The ferry was pulled over the river by a man with a rope line. It cost $10.00 to cross, which included a wagon and 2 persons with an additional charge $0.50 for each additional person. A post office was founded in 1881 and operated until 1906

On July 8, 1879, the steamboat Gila, piloted by Captain Jack Mellon, made Rioville the uppermost landing for steamboats of the Colorado River. The arrival made the town high water head of navigation on the Colorado River and Captain Mellon finally proved that it was indeed the head of steam navigation on the Colorado River. The
Mormon population in town were “wonder-struck” to see a steamboat; one proclaimed it the “biggest thing he ever saw in water.”

Steamboats continued to traffic high up the Colorado River until 1887 when silver mining activity declined during high water months. The town was service from 1879 to 1882 the the sloop Sou’Wester during low water, carried locally mined salt to process silver ore in El Dorado Canyon. From 1869 to 1887, the landing at Rioville was the High Water of Navigation for steamboat traffic on the Colorado River, which was 440 miles from Fort Yuma.

The town was abandoned in the 1890s but the post office lingered to 1906 and the ferry until 1934. The rising waters of Lake Mead, caused by the construction of Hoover Damn drowned the location in water.

Nelson Nevada and Eldorado Canyon – Clark County Ghost Town

Nelson, Nevada, is a small unincorporated community in Clark County, located in the rugged hills of El Dorado Canyon about 45 minutes south of Las Vegas along Nevada Highway 165. The canyon itself drains into the Colorado River (now part of Lake Mohave) and is best known for the historic Techatticup Mine—one of the oldest, richest, and most famous gold mines in southern Nevada. Together, Nelson and El Dorado Canyon represent a classic chapter in Nevada’s mining heritage: from early Spanish exploration and a violent 19th-century gold rush to 20th-century wartime production and today’s preserved tourist site. What began as a remote, lawless mining district became one of the most productive areas in the state’s southern history.

Pre-European History and Early European Contact

Long before miners arrived, the area was home to Ancestral Puebloans, followed by Paiute and Mojave tribes who lived along the Colorado River corridor for centuries. In 1775, Spanish surveyors exploring the canyon along the Colorado River discovered rich deposits of gold, silver, and lead. They named the canyon “Eldorado” (Spanish for “golden”) and established a small settlement at the river’s mouth, but the silver quantities proved too low to sustain operations, and they soon moved on—missing the far richer gold veins hidden in the canyon walls.

The 19th-Century Mining Boom (1850s–1870s)

Serious prospecting began in the 1850s when American miners sluiced streams feeding the Colorado River. In 1857–1858, steamboat captain George Alonzo Johnson formally named the canyon El Dorado after noting gold and silver deposits. The real rush ignited in April 1861 when Mojave Chief Irataba guided prospector John Moss to a rich silver (and gold/copper) vein. Word spread rapidly, triggering one of the largest mining booms in southern Nevada history and the formation of the Colorado Mining District (later called the Eldorado Canyon District).

The Salvage Vein—a vertically stacked ribbon of ore—became the focus. The most famous operation was the Techatticup Mine (named from Paiute words meaning “hungry” or “bread,” because local Paiutes came to the camps begging for food). Other key mines included the Wall Street, Queen City, Gettysburg, and Savage. These produced millions of dollars in gold, silver, copper, and lead over decades. Ore was initially shipped by steamboat down the Colorado River to Yuma, Arizona, and then to San Francisco. A 10-stamp steam-powered mill (the first in the canyon) was built in 1863 at El Dorado City near the river, cutting transportation costs.

Several mining camps sprang up: San Juan (upper canyon, near modern Nelson), Alturas and Louisville (mid-canyon near Techatticup), and Colorado City/El Dorado City at the river landing. During the Civil War, the area even hosted rival camps—Lucky Jim (Confederate sympathizers) and Buster Falls (Union)—highlighting the national divisions that spilled into the remote desert.

Lawlessness and the “Wild West” Reputation

El Dorado Canyon earned a notorious reputation for violence that rivaled Tombstone, Arizona. Its extreme isolation—hundreds of miles from the nearest sheriff in Pioche or Hiko—meant law enforcement rarely ventured in. Claim-jumping, shootings over ownership and labor disputes, greed, and vigilante justice were daily occurrences. Many miners were Civil War deserters seeking anonymity. Murders were so common that they barely made headlines. The U.S. Army established Camp El Dorado in 1867 at the canyon mouth to protect steamboat traffic and deter Paiute raids, but it was abandoned two years later.

Infamous figures included Paiute renegade Ahvote and Cocopah serial killer Queho, who murdered over 20 people in the early 1900s (one victim near the Techatticup Mine in 1919). Locals formed posses for justice when authorities could not respond.

The Rise of Nelson and 20th-Century Operations

The original riverfront town of Eldorado gradually declined after the 1870s. In 1905 a new hub emerged about seven miles up-canyon and was named Nelson (after early settler Charles Nelson). A 50-ton smelter was built, sparking a second boom. Mining slowed in the early 1900s but revived in the late 1930s to supply ore for the U.S. military during World War II. The Techatticup Mine—the longest-lived and most productive in the district—finally closed around 1941–1945 due to rising labor costs.

The construction of Davis Dam in the 1950s created Lake Mohave, flooding the old Nelson’s Landing, stamp mill site, and lower canyon. The historic cemetery was relocated one mile upstream to avoid inundation

Modern Era and Tourism

Today, only about 35 people live in Nelson, a quiet cluster of homes and remnants of the mining past. The Techatticup Mine site (51 acres) was purchased in 1994 by Tony and Bobbie Werly and their family. They restored buildings, cleared tunnels, installed lighting and safety features, and opened guided tours that explore both above- and below-ground sections (about 500 feet deep). The site now functions as a museum and living-history attraction with antique vehicles, mining artifacts, a gift shop, and even a wedding chapel. It has also served as a filming location for movies such as Breakdown (1997) and 3000 Miles to Graceland (2001), whose crashed airplane prop remains on display.

El Dorado Canyon is no longer an active mining district but a scenic desert landscape popular with hikers, photographers, and history buffs. Visitors can explore the preserved “ghost town” feel—rusting machinery, weathered buildings, and canyon views—while remembering its turbulent past of riches, bloodshed, and resilience.

Founded in 1905 Nelson, Nevada is located some seven miles west at the head of Eldorado Canyon. The town of Nelson slumped for two decades beginning in 1909, but the 1930’s found a resurgence in gold production. By 1941, the three cyanide mills processed 220 tons of ore daily. The population reached 600 persons, however increased costs caused the gold production to slow and eventually cease. The Techatticip mine produced over half of the total gold produced in the area. The gold produced by the region has an estimated valued at $10,000,000.00.

In 1951, Davis Damn is completed. The original town site in Eldorado canyon was buried and drowned by the rising waters of Lake Mojave.

Today

Today, the town of Nelson hosts some 37 people in the 2010 census. The older section of town hosts many old buildings, ruins, cars, mining equipment and all in all is an eclectic collection of mining and western history. The current occupants have a wonderful collection of old mining gear and western history, mixed with an eclectic collection of art.

Conclusion

From Spanish dreams of El Dorado in 1775 to the chaotic gold rush of the 1860s, Civil War tensions, and World War II production, Nelson and El Dorado Canyon encapsulate the boom-and-bust cycle of Nevada mining. The Techatticup Mine’s millions in precious metals helped shape the American West, even as lawlessness and isolation defined daily life. Today, the restored site offers a safe window into that wild history—just a short drive from Las Vegas—preserving the stories of the miners, outlaws, and dreamers who once called this canyon home. For those interested in touring, reservations are required through Eldorado Canyon Mine Tours.

Nelson, Nevada is a quiet destination worthy of a few hours if you are in the area.
