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.

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.
