Wildfires raging near the Grand Canyon National Park in Arizona have expanded dramatically, forcing evacuations and threatening historical sites. The White Sage Fire has burned over 20,000 acres, while the Dragon Bravo Fire poses a separate threat. Simultaneously, Canadian wildfire smoke has caused unhealthy air quality across the Upper Midwest, impacting outdoor activities and prompting health warnings. High temperatures and dry conditions exacerbate the fire risk, with officials urging caution. Multiple wildfires are also burning in other states, leading to further evacuations and park closures.
