Yankee Fork Gold Dredge Road — Custer to Jordan Creek via Salmon River Mountains
Ghost dredge, shale shelves, and Idaho high country.
The Yankee Fork Road follows the Yankee Fork of the Salmon River north from the ghost town of Custer into the heart of the Salmon River Mountains, passing one of the most intact gold dredges in the American West — the Yankee Fork Gold Dredge, a 988-ton hulk that chewed through this canyon from 1940 to 1952 and left a trail of rock tailings that still scar the valley floor. Past the dredge site, the road tightens and climbs through lodgepole and spruce before reaching open ridgelines above ten thousand feet. The route connects to Jordan Creek and the broader Custer Motorway network, but the stretch along the upper Yankee Fork drainage — narrow shelf road with loose shale and creek crossings — is the part that earns the mileage.
High-clearance 4×4 is required above the dredge; the lower section is graded gravel accessible to most rigs in dry conditions. The upper road gets rough fast with ruts, embedded rock, and creek crossings that run high through June. Best season is July through September — snow can close the high sections through early summer. No permits required for the road itself. Fuel up in Challis before heading in; it’s the last reliable stop. The Salmon-Challis National Forest manages this corridor. Dispersed camping is allowed in most areas along the route. Cell service is nonexistent above the valley floor.

Frequently asked questions
Can a stock Tacoma or 4Runner run Yankee Fork Gold Dredge Road without modifications?
A stock high-clearance 4x4 like a Tacoma or 4Runner can handle this trail, but the shale shelf sections and rocky climbs toward the 9,800-ft high point will punish low-clearance rigs. Skid plates are a good idea — you will drag something if you don't have them.
When does this route typically open and close for the season?
July through September is the reliable window. Snow lingers at the upper elevations well into June, and early October storms can shut the high sections down fast. Don't count on it being passable before the Fourth of July.
Do you need a permit or pay any fees to drive this route?
No permit required and no day-use fee to drive the road. Dispersed camping on Salmon-Challis National Forest land is free; standard forest rules apply — no camping within 200 feet of water sources or the road.
What's the hardest section of the trail and what makes it gnarly?
The shale shelf roads on the upper ridgeline are the sketchiest part — loose, off-camber slabs with exposure on the downhill side and no room to turn around easily. It's not a death-defying obstacle, but one wrong line on wet shale will put you on your side.
Are the water crossings on this route actual drive-throughs, and how deep do they run in peak season?
Yes, there are real drive-through crossings — primarily along the Yankee Fork of the Salmon River corridor. In July during a heavy snowpack year they can run knee-deep or more; by late August they're typically ankle-deep and straightforward for a high-clearance 4x4. Check snowpack data for the Salmon River Mountains before you go if you're running it early season.
