South Pass Country — The Gold-Rush Ghost Town, the Continental Divide & the Emigrant Trails

One of the best-preserved gold-rush towns in the American West, South Pass City sprang up almost overnight after gold was struck in the Carissa lode in 1867, swelling to a few thousand prospectors before the ore played out and the town emptied. Wyoming's state historic site preserves more than 20 original buildings along the single dirt main street — the saloon, the hotel, the general store, the schoolhouse, and cabins — many with their original furnishings still in place, so it feels less like a museum than a town its people simply walked away from. The restored Carissa Mine and stamp mill can be toured on the hill above. South Pass City also holds a landmark of another kind: it was here that Esther Hobart Morris, and the territorial legislator William Bright who represented the district, helped make Wyoming the first place in the world to grant women the full right to vote in 1869. Plan a couple of hours to walk the whole town.

Use the afternoon to explore a different side of South Pass City State Historic Site — there's more to discover beyond the morning highlights.

Above the townsite stands the Carissa Mine, the gold strike that gave birth to South Pass City and worked on and off for nearly a century until the 1950s. Stabilized and preserved by the state, the towering weathered mill building houses the original stamp mill — the massive machinery that crushed gold ore — and seasonal ranger-led tours walk visitors through the milling process and the hard, dangerous life of a hard-rock miner. It is a rare chance to step inside an authentic frontier gold mill rather than a reconstruction. Tour availability is seasonal and weather-dependent; check at the visitor center when you arrive. Sturdy shoes are recommended for the mine hill.

A mile from South Pass City, Atlantic City is the ghost town's still-breathing twin — founded in the same 1868 gold rush but never fully abandoned, so that today a handful of residents, a historic church, a pioneer cemetery, and the weathered false-front Atlantic City Mercantile (dating to 1893) survive along its dirt lanes. Where South Pass City is a curated state site, Atlantic City is the real, lived-in article, its old buildings leaning into the sagebrush hills. Wander the lanes, read the cemetery stones, and step into the Mercantile if it is open. The contrast between the two towns — one preserved, one persisting — is the heart of the morning.

South Pass itself is the reason all of this history exists: a broad, gentle 20-mile-wide saddle over the Continental Divide at about 7,400 feet, so gradual that emigrant wagons could cross the spine of the Rockies without a mountain climb. Between roughly 1843 and 1869, an estimated 400,000 people on the Oregon, California, and Mormon Trails funneled through this single gap — the greatest voluntary migration in American history. Interpretive pullouts along Highway 28 mark the crossing, and short walks lead to visible wagon ruts still worn into the sage, and to trail landmarks such as the Parting of the Ways, where the California and Oregon routes split. Nearby monuments honor Narcissa Whitman and Eliza Spalding, the first white women to cross the Divide here in 1836. Standing on this quiet, windswept ground, it is easy to feel the sheer scale of the westward movement that passed through.

The Fremont County Pioneer Museum in Lander ties the whole trip together, with strong holdings on the very emigrant trails and gold rush this journey has traced. Exhibits cover the Oregon, California, Mormon, and Lander Trails that crossed the county, the South Pass and Atlantic City gold mining era, homesteading and ranching, and the region's Native peoples. Look for the pioneer artifacts, wagon-era relics, and photographs of South Pass City in its boomtown heyday. It is a substantial, well-kept local museum and the ideal place to consolidate three days of trail-and-gold-rush history before the last stop. Confirm hours, which narrow in the off-season.

Just south of Lander, the Middle Fork of the Popo Agie River performs one of Wyoming's strangest natural tricks: at the 'Sinks,' the whole river roars into a cave in the canyon wall and vanishes underground, then re-emerges a quarter-mile down the canyon at the 'Rise,' a calm spring pool full of large trout. Curiously, dye tests show the water takes about two hours to travel between the two points and more water comes out than goes in, and it emerges warmer — a puzzle geologists have never fully solved. A state park visitor center explains the karst geology, and short walks connect the Sinks to the Rise, where you can feed the trout that crowd the pool. It is a memorable, unhurried final stop — deep-time geology to close a trip that began with human history — before the drive back over the mountains to Jackson.
