From Randle WA, take South 131. Then follow the signs that lead to Cispus Learning Center. About 1/2 mile after crossing the Cispus river, about a mile before the CLC there is a bridge over Yellow Jacket Creek.
There is parking for 4 to 5 vehicles near the bridge. The claim access is pretty easy from here, just hike along the waterline to the SE until you find a likely spot. The printed guide recommends turning up USFS #29, but then there is a tough descent from that parking area to access the creek. And a tougher climb to get back to your vehicle.
