Astonishing pictures show “wall fire” burning through a residential area in California │ Hundreds of people were ordered to evacuate from fast-moving wildfires burning through steep terrain in California on Saturday, after searing temperatures and parched land fuelled dozens of blazes. Residents from Oroville were evacuated as the so-called Butte County Wall Fire continued to grow. They said at least six people have been injured and 10 structures destroyed. Heavy rainfall in parts of the West over the winter and spring helped delay the onset of the fire season, but also spurred the growth of dense vegetation that has dried out and become highly combustible in summertime heat.
