Deadly fire shuts down key route to Yosemite National Park

MARIPOSA, Calif. — A wildfire that killed a California firefighter grew quickly and forced the closure of a key route into Yosemite National Park as crews contended with sweltering conditions Sunday, authorities said.The blaze that broke out Friday scorched more than 6 square miles of dry brush along steep, remote hillsides on the park's western edge. It was burning largely out of control, and officials shut off electricity to many areas, including Yosemite Valley, as a safety precaution.G
