Wildfires in the American West, including one burning in Oregon that's currently the largest in the U.S., are creating hazy skies as far away as New York as the massive infernos spew smoke and ash into the air in columns up to 6 miles (10 kilometers) high. Skies over New York City were hazy Tuesday as strong winds blew smoke east from California, Oregon, Montana and other states. Oregon's Bootleg Fire grew to 616 square miles (1,595 square kilometers), AP reported. Fires also grew on both sides of California's Sierra Nevada. The Dixie Fire, which broke out near the site of the 2018 Camp Fire that killed 85 people in the town of Paradise, ballooned to more than 133 square miles (344 square kilometers), with 15% containment. More than 800 structures were threatened. In Alpine County, known as the California Alps, the Tamarack Fire caused evacuations of several communities and grew to 61 square miles (158 square kilometers) with no containment.
