Citation from California Office of Historic Preservation
Sulphur Bank Mine closed in 1957 and is now a superfund site.
We could not locate the commemorative plaque, but we did obtain a photograph from the Center for Sacramento History which shows that the plaque was dedicated in 1950 and was still in place in 1957.
One generation's cause for celebration is too often the next generation's source of regret.
