Providence Mountains State Recreation Area (Mitchell Caverns) is closed indefinately
Meanwhile, shortfalls in the California state budget caused lawmakers in Sacramento to ask that state agencies identify possible budget cuts. In May 2011, California State Parks released its closure list, and Providence Mountians was among the 70 parks included. Although closures for most parks on the list won't go into effect until July 2012, California State Parks officials decided not to invest in repairs to the park's infrastructure during a time of skrinking budgets, so Providence Mountains State Recreation Area remains closed.
With continuing weakness in the economy and ongoing fiscal issues for California State Parks, the future of Mitchell Caverns remains uncertain.
