Forty Mile Desert
Churchill County, Churchill County, Nevada
Marker Inscription
Forty Mile Desert. The Forty Mile Desert, beginning here, is a barren stretch of waterless alkali wasteland. It was the most dreaded section of the California Emigrant Trail. If possible, travelers crossed it by night because of the great heat.In 1843, the Walker-Chiles Party became the first wagon train to use the route. Regardless of the desert’s horrors, this became the accepted trail, as it divided five miles southwest of here into the two main routes to California - the Carson River and Truckee River trails.Starvation and thirst preyed upon people and animals every mile. A survey made in 1850 illustrated appalling statistics - 1,061 dead mules, almost 5,000 horses, 3,750 cattle, and 953 graves. The value of personal property loss was set at the time at $1,000,000.The heaviest traffic occurred between 1849 and 1869. The trail was still used after completion of the Central Pacific Railroad in 1869, although it saw declining traffic after that.

The Story
The Forty Mile Desert, beginning here, was a barren stretch of waterless alkali that emigrants regarded as the most dreaded section of the California Trail — many crossed it by night to escape the punishing heat. The Walker-Chiles Party first brought wagons through in 1843, and despite its horrors the route became the accepted path, splitting into the Carson and Truckee River trails. An 1850 survey tallied the grim toll: more than 1,000 dead mules, nearly 5,000 horses, thousands of cattle, and 953 graves.
Why it matters
This deadly stretch was the final gauntlet of the overland journey, where the westward dream was tested against thirst, heat, and death.
The story behind this marker
AI contextThe era
By the middle of the nineteenth century, the young United States had convinced itself that its destiny ran clear to the Pacific. Families sold farms in Missouri and Ohio, packed everything they owned into canvas-topped wagons, and pointed their oxen west toward Oregon and California. The overland trail was long, but for most of its length there was grass, and there was water.
That promise ran out here. This corner of what is now Churchill County sits at the edge of the Great Basin, a vast bowl of desert where rivers vanish into the sand instead of reaching the sea. The land you are standing on was once the floor of an enormous Ice Age lake; when the water evaporated, it left behind a flat, glittering crust of alkali that holds no drinking water and grows almost nothing.
For emigrants who had already spent months on the trail, this stretch was the cruelest surprise of all — a final barrier thrown down within reach of the goldfields and green valleys of California. Many timed their crossing for the dark, moving through the night to spare their exhausted animals the worst of the sun, then pushing on toward the promise of the next river.
People & events
The route across this desert did not appear on any map when the first wagons attempted it. In 1843 the Walker-Chiles party came through, becoming the first wagon train to use the crossing — and in doing so they helped fix the path that thousands would follow after them.
A few miles from here the trail forked, splitting travelers toward two different rivers and two different mountain passages into California. The choice mattered enormously, but both roads began with the same ordeal: the waterless plain in front of you.
The cost of that ordeal was recorded with grim precision. A survey taken in 1850 counted the carcasses of thousands of horses, mules, and cattle scattered across the sand, along with hundreds of human graves. Abandoned wagons and discarded belongings — furniture, tools, trunks carried all the way from home — littered the route, worth a fortune at the time and left behind because a thirsty animal cannot pull dead weight. The people who survived did so by traveling light, moving fast, and trusting that water lay ahead.
Its place in the American story
The overland migration to California is one of the defining chapters of the American story, and this desert was its final examination. Everything the westering dream promised — new land, new fortune, a fresh start — had to be paid for here, in the hardest currency the trail demanded.
The traffic peaked in the two decades after 1849, when the discovery of gold turned a steady stream of settlers into a flood. Every one of those hopeful travelers who took this southern route had to reckon with the crossing, and the graves counted in that 1850 survey are a reminder that the frontier's rewards were never guaranteed.
The wagons kept rolling even after the transcontinental railroad was completed in 1869, though their numbers dwindled as the rails offered an easier way west. In that shift you can watch an era end: the slow, dangerous, deeply human passage of the wagon train giving way to the age of steam. The dread this desert inspired is a measure of just how much ordinary people were willing to risk to reach the other side of the continent.
If you visit
Stand here for a moment and look out across the flat, pale ground. What strikes most visitors first is the silence and the emptiness — the same emptiness that made this the most feared leg of the journey. Try to imagine it not as scenery but as an obstacle you had to walk across, on foot, beside failing animals, with the nearest water a full day away.
The desert is best appreciated with respect. Come prepared as any traveler here always had to be: carry more water than you think you need, and be mindful of the heat, which is exactly the enemy the emigrants tried to outrun by moving at night.
This is a natural stop on a drive across northern Nevada, and it rewards the pause. Reading about a thousand-mile migration is one thing; feeling the scale of the country that migration had to cross is another. Standing at the edge of the crossing, with the mountains that promised relief just visible in the distance, you get a little of what those travelers felt — the fear of what lay ahead, and the pull of what lay beyond it.

Pershing County
Lovelock, NV
This lush valley — the Big Meadows — was a vital rest stop on the Humboldt Trail, the route that carried some 165,000 emigrants west in the 1840s and 1850s. Travelers gathered water and grass here before facing the dreaded Forty Mile Desert, the trail's cruelest stretch. Mining began in the 1850s, merchant-rancher George Lovelock lent his name to the county seat, and the railroad's arrival in 1869 brought fresh growth; Pershing County itself was carved from Humboldt County in 1919.
Hazen
Churchill County, NV
Hazen sprang up in 1903 as a rough-and-tumble camp housing laborers on the federal Newlands irrigation project, one of the first reclamation efforts to green the Nevada desert. When the railroad to Tonopah arrived in 1905 and the Southern Pacific built a roundhouse and depot the next year, the town of hotels, saloons, and brothels boomed—alongside a reputation for lawlessness that included the 1905 lynching of 'Red' Wood. Fire nearly wiped it out in 1908, and the town named for Civil War general William B. Hazen never fully recovered.
Stillwater
Churchill County, NV
Named for the calm pools nearby, Stillwater took shape as an overland stage station in 1862 — two years before Nevada's statehood — gained a post office in 1865, and became Churchill County's third county seat in 1868. Its population peaked around 1880, and when the seat moved to Fallon in 1904 barely thirty residents remained. Though its town center is gone, the valley's fertile fields still testify to its pioneer ranchers, and the 163,000-acre Stillwater National Wildlife Refuge, created in 1949, now adjoins the Stillwater Indian Reservation.
Ragtown
Churchill County, NV
Ragtown was never truly a town but a beloved oasis on the Carson River, its name drawn from the pioneer laundry draped across every bush by emigrants who had just survived the Forty-Mile Desert. For thirst-crazed travelers and their animals, the cottonwoods lining the river were the first water after the trail's most dreaded crossing. In 1854 Asa Kenyon set up a trading post nearby, and through the 1850s and 1860s Ragtown ranked among the most important stops on the Carson branch of the California Trail.
