Firefighters are battling multiple wildfires across the western United States, with the largest being the Park Fire in northern California, which has burned over 400,000 acres and is 34% contained. Hot and dry conditions are expected to challenge efforts to control the blaze, which has destroyed 640 structures. In San Bernardino County, the Edgehill Fire has prompted evacuations and burned several homes. Colorado's Front Range is also facing significant wildfires, including the Alexander Mountain, Stone Canyon, and Quarry fires, which have collectively burned nearly 12,000 acres and resulted in one fatality. Progress has been made in containment, with the Stone Canyon fire fully contained and evacuation orders lifted. Authorities are investigating the causes of these fires, with some suspected of arson.
