A dust storm disrupted the Burning Man festival in Nevada on Saturday, a spokesman for the federal Bureau of Land Management, Roger Farschon, told The Associated Press. The festival was in a “total whiteout,” Mr. Farschon said in an e-mail message. “A similar cold front caused a major dust event on Monday. The rest of the event has been relatively dust-free.” The festival, a celebration of music, art and self-expression held in the Black Rock Desert, attracts nearly 50,000 participants each year.
