Land of the Yankee Fork State Park
Highway 75 and Highway 93 Junction
Challis, ID
A whole valley of Idaho gold-rush history, from two atmospheric ghost towns to a 988-ton dredge that chewed up the Yankee Fork for gold as late as 1952.
Land of the Yankee Fork is less a single park than an entire chapter of Idaho history spread across the Salmon River mountains. It gathers the ghost towns of Custer, Bonanza, and Bayhorse together with the extraordinary Yankee Fork Gold Dredge, all of it telling the story of the gold and silver rushes that pulled people into this rugged country in the 1870s.
The centerpiece is the dredge itself, a 988-ton behemoth that was shipped in pieces from Minnesota, assembled on site in 1940, and set loose to dig up the gravels of the Yankee Fork in search of gold as recently as 1952. It left behind long ridges of tailings you can still see today, and standing next to it you understand just how far people would go to chase a little color out of a mountain stream.
What Guests Love
- Walking the weathered streets of Custer and Bonanza, two genuine 1870s mining ghost towns
- Standing beside the enormous Yankee Fork Gold Dredge, a floating gold factory the size of a building
- The gold-panning station and mining exhibits at the Challis interpretive center
- A remote, mountain-ringed setting that still feels like the edge of the frontier
Worth Knowing
- The dredge and ghost towns are up an unpaved road that is typically open only in the warmer months and can be rough, so check conditions before you go
- This is high, remote country with long distances between services, so fuel up and carry water
- The ghost-town buildings are fragile historic structures, so look but tread lightly
- Winter closes much of the upper park, and the interpretive center keeps a seasonal schedule

The story of the Yankee Fork rush
Long before miners arrived, this was the homeland of the Shoshone-Bannock people, who traveled the Salmon River country following fish, game, and the seasons, and whose descendants remain a living presence in Idaho today.
Gold on the Yankee Fork, a tributary of the Salmon River, set off a rush in the mid 1870s. In 1879 lots were sold and the town of Custer grew up as the support center for the General Custer, Lucky Boy, and other mines. At its peak around 1896 Custer counted several hundred residents, with stores, saloons, and a school.
By the early 1900s the ore was playing out, and one by one the mines closed. Custer emptied and became a ghost town, while nearby Bonanza, once the larger of the two, had already been gutted by fire in the 1890s. What remains is a rare, quiet snapshot of a boomtown that simply stopped.
The gold dredge
The Yankee Fork Gold Dredge is the park's unforgettable object. Built to work ground the old miners could not reach, it floated on a pond of its own making, scooping gravel with a chain of buckets, washing out the gold, and dumping the spoil out the back.
Roughly 988 tons of steel, it worked its way along a claim several miles long through the 1940s and into 1952. The ridges of cobble it piled along the valley floor are its lasting signature, a reminder that the last great push for Yankee Fork gold came within living memory, not the distant past.
Wildlife and the high country
The park sits in classic central Idaho backcountry, ringed by the Salmon River Mountains and not far from the Sawtooths. The Yankee Fork and the main Salmon carry trout and, in season, migrating salmon and steelhead that have traveled hundreds of miles from the Pacific.
Mule deer, elk, and pronghorn range the sagebrush and timber, golden eagles ride the ridgelines, and the night skies out here are among the darkest in the Lower 48.
When to visit
Summer and early fall are the season here, when the Yankee Fork Road is open and the dredge and ghost towns are accessible. Wildflowers color the high meadows in early summer and the aspens turn gold in September.
Come prepared for mountain weather that can shift quickly, and remember that snow closes the upper valley for much of the year. The Challis interpretive center is the place to start and to check current road and site conditions.
