There is a washout on the WABDR in Section 5 (Chelan/Conconully) going north past Cooper Mountain on the way to Fox Peak and the Carlton Store. Washout coordinates - N48.12024 W120.17921.
Big bikes are warned to avoid this washout as it is challenging to get through and construction teams working on repairs might block passage anyway.
The alternate route for now would be to descend the ridge well before reaching Fox Peak. The best route we see is via Black Canyon Creek on Forest Road 4010. This will put riders on Highway 153 farther east of Carlton.
