In 2013, Save Mount Diablo, an environmental group, purchased Curry Canyon Ranch, a scenic, 1,080-acre property that borders Mount Diablo State Park on three sides, for $7.2 million, intending to sell it to the state parks department at or below cost. State parks officials say now they can’t afford to buy it, however, leaving the public without access. (Photo: Scott Hein, Save Mount Diablo)
