(Grist) - It was a sweltering, 117-degree July day in Hinkley, California. The surface of the 13-mile highway east to Barstow had become an asphalt skillet, and the town’s lone recreational feature, a children’s playscape, stood shining and unused like a monument to the lofty melting point of low-density polyethylene. Residents here appreciate the dry, desert landscape — that’s why many moved to Hinkley in the first place — but on days like this everyone takes refuge indoors, curtains drawn against the view of empty lots where neighbors’ houses once stood. Along the empty roads, thousands of pipe stubs — groundwater monitoring wells installed by Pacific Gas and Electric — began to look like air vents to some underground bunker where most everyone in town had retreated.
