Juvenile Western Bluebird at the Black Diamond Mine
from the number of posts I've put up (this is the 13th).
Black Diamond Mine was a source of coal and glass-making sands a century ago (California is not known as being much of a coal mining region, but the energy demands in the late 1800s led to the use of even marginal coal deposits). The park is a pleasant place for hiking and bird-watching. Many of the scars of the mining have faded away.
