Wikipedia:Articles for deletion/Willow Valley, California
I think this clearly passes  based on a newspapers.com source search with articles such as the obituary https://www.newspapers.com/image/619253753/ here showing it's understood to be a community, and https://www.newspapers.com/image/619269855/ showing it was at least a voting precinct. Even if this isn't a community and rather a geographic feature (which I doubt) there's heaps of coverage about the mining and school in the vicinity
