From the record
“The Douglas Flat School is a historic school building on California State Route 4 in Douglas Flat, California. The school was built in 1854 to serve miners who settled in Douglas Flat during the California Gold Rush; the school site was the only place in Douglas Flat where mining was not permitted, as the mining rights on the property were reserved for the first teachers.”
