The Denver skyline is barely visible through a train bridge on Sixth Avenue in Lakewood, Colo., as smoke from the wildfire in Arizona fills the air on Monday, June 6, 2011. Kyle Fredin, a meteorologist for the National Weather Service in Denver, said that a ridge of high pressure was carrying the smoke as far away as central Iowa. He said the smoke was also hitting eastern Colorado _ where it obscured the view of the mountains from downtown Denver _ as well as New Mexico, Nebraska and Kansas. (AP Photo/Ed Andrieski) less
