Potosi
Clark County, Clark County, Nevada
Marker Inscription
Potosi. The desire of local Mormon settlers for economic self-sufficiency led to mining by missionaries for lead at Potosí. In 1858, Nathaniel V. Jones was sent to recover ore from the “mountain of lead” 30 miles southwest of the mission at Las Vegas Springs. About 9,000 lbs. were recovered before smelting difficulties forced the remote mine to be abandoned in 1857. Potosi became the first abandoned mine in Nevada.In 1861, California mining interests reopened the mine, and a smelter and rock cabins for 100 miners made up the camp of Potosi. Even more extensive operations resulted after the transcontinental Salt Lake and San Pedro R.R. (now the union pacific) was built through the county in 1905.During World War I, Potosi was an important source of zinc.

The Story
Seeking economic self-sufficiency, Mormon settlers turned to mining lead at Potosi in the late 1850s, when Nathaniel V. Jones was dispatched to work the “mountain of lead” southwest of the Las Vegas mission, though smelting troubles soon forced the remote mine to close—making it the first abandoned mine in Nevada. California interests reopened it in 1861, building a smelter and stone cabins for a hundred miners, and operations expanded further after the transcontinental railroad reached the county in 1905. During World War I, Potosi served as an important source of zinc.
Why it matters
Potosi links the Mormon drive for self-reliance, the railroad's transformation of remote mining, and the nation's wartime hunger for metals, all layered onto one southern Nevada mountain.
The story behind this marker
AI contextThe era
In the middle of the nineteenth century, the stretch of desert around present-day southern Nevada was one of the emptiest and most demanding corners of the American West. Water was scarce, distances were punishing, and the nearest settled outpost was the small Mormon mission at Las Vegas Springs, planted to serve travelers on the road between Salt Lake City and southern California. For the settlers there, self-sufficiency was not an ideal but a necessity — supplies hauled across hundreds of miles of desert were slow, costly, and never guaranteed.
That hunger for independence turned their eyes to the mountains. Lead was one of the humblest but most essential metals of frontier life: it meant bullets for hunting and defense, and material for countless everyday needs. A nearby height so rich in the mineral that it was called a "mountain of lead" promised a homegrown source, and the mission set out to work it rather than depend on distant markets.
The attempt came at the tail end of the 1850s, an era when Americans were pushing mining ventures into ever more remote ground, often before the roads, fuel, and skilled labor needed to sustain them had arrived. Potosi sits squarely in that pattern — an ambitious reach into difficult country during the years historians call the Early Republic giving way to a more industrial age.
People & events
The figure at the center of the early story is Nathaniel V. Jones, dispatched to recover ore from the lead mountain some thirty miles southwest of the Las Vegas mission. His task was straightforward in principle and grueling in practice: pull metal from a raw deposit in a place with almost nothing to support the work. Roughly nine thousand pounds of ore were brought out before the effort collapsed.
What undid it was not the ore but the smelting — the delicate, fuel-hungry process of turning rock into usable metal. In a location this isolated, the difficulties proved too much, and the mine was abandoned. In doing so it earned an unusual distinction: the first abandoned mine in Nevada, a monument to how quickly frontier optimism could run up against hard limits.
The mountain did not stay quiet for long. In 1861, California mining interests reopened the site, and this time a genuine camp took shape — a smelter to process the ore and rock cabins built for around a hundred miners. Potosi's fortunes rose again after the transcontinental Salt Lake and San Pedro railroad, later part of the Union Pacific, was pushed through the county in 1905, opening the remote district to far more ambitious operations. During the First World War, the mountain answered a new national demand, becoming an important source of zinc.
Its place in the American story
Potosi is a compact lesson in how the American West was actually built — not in a single rush, but in layers, each driven by a different national need. First came the settler's dream of self-reliance, the same impulse that scattered small, striving communities across the arid interior. Then came outside capital, the California interests who understood that mineral wealth in the desert was worth pursuing once someone was willing to fund the smelter and the cabins.
The railroad chapter is the pivotal one. Across the West, remote deposits that had defeated earlier miners suddenly became workable the moment steel rails reached them, because ore could finally move and supplies could finally arrive. Potosi's revival after 1905 mirrors that transformation playing out on countless mountainsides — the railroad, more than any single strike, is what turned scattered prospects into working industry.
The wartime zinc chapter closes the circle, tying one obscure Nevada mountain to the enormous industrial appetite of a nation at war. It is a reminder that the metals feeding factories and munitions plants came from exactly such out-of-the-way places, and that the story of American power runs straight through the desert diggings most travelers would never think to notice.
If you visit
Come to Potosi for the long view — of both the landscape and the history layered into it. You are in high desert country southwest of the Las Vegas valley, and the first thing to take in is the sheer remoteness that shaped everything here. Picture hauling ore, fuel, and every scrap of equipment across this ground by wagon, and the marker's story of a mine abandoned for "smelting difficulties" stops sounding like failure and starts sounding inevitable.
Look to the surrounding heights and imagine them as the "mountain of lead" that drew people again and again. Watch, too, for the faint signatures of old mining country — disturbed ground, tailings, the ghost of a camp that once housed around a hundred miners. Treat any ruins or old workings with care and from a distance; abandoned mine sites can be genuinely dangerous, and the historic traces are fragile.
It makes a rewarding stop for anyone tracing the deeper history behind modern southern Nevada. Before the neon, this was a place where settlers chased self-sufficiency, outside money chased ore, and a railroad finally chased away the isolation. Standing here, you can hold all three eras at once — the quiet desert doing a much better job of keeping that history than the bustle a few dozen miles away.

Goodsprings Mining District 1856 1957
Clark County, NV
The folded limestone of this district held ore that went unworked until the mid-1850s, when Mormon settlers opened work at Potosi, among the earliest underground mines in Nevada. Named for cattleman Joseph Good, the springs grew into the ranching-and-mining community of Goodsprings, and the arrival of the Los Angeles-Salt Lake Railroad in 1905 and a narrow-gauge feeder line in 1911 cut the cost of shipping its zinc ores. Operations peaked in 1916 with some eight hundred residents, and the district—unusually rich in minerals—ultimately produced about twenty-five million dollars, chiefly in lead and zinc.
The Morelli House
Las Vegas, NV
Built in 1959 by Sands Hotel orchestra leader Antonio Morelli and his wife Helen, this home is a polished example of Las Vegas mid-century modern design — open-plan living that blurred indoors and out, natural materials, and the newest home appliances of the era. It originally stood in the Desert Inn Country Club Estates, a neighborhood later swallowed by the Wynn resort. In 2001 the Junior League of Las Vegas moved the house to its present site, completing restoration in 2009.
Eldorado Canyon
Boulder City, NV
Eldorado Canyon runs east to the Colorado River, and around 1859 prospectors began digging its slopes for gold and silver, organizing the Colorado Mining District. Its three great mines — the Techatticup, Wall Street, and El Dorado Rand — yielded more than six million dollars, while steamboats and barges freighted goods some 350 miles up from the Gulf of California to the canyon's mouth. In 1867 the U.S. Army planted an outpost here to guard the river freight and the miners; the mines revived in the 1870s and worked on until World War II.
Hoover Dam Memorial
Clark County, NV
Completed in 1935 across the Colorado River's Black Canyon, Hoover Dam was one of the greatest engineering feats of its age, built during the Great Depression to tame floods, store water, and generate hydroelectric power for the fast-growing Southwest. Thousands of workers labored in brutal desert heat to raise its massive concrete arch, and many died in the effort this plaque honors.
