Heavy winds that swept through Black Canyon of the Gunnison National Park on Sunday night started “rapid fire spread” after a relatively slow day of growth, according to fire officials.

The South Rim Fire has burned more than 3,600 acres uncontained since sparking Thursday along the canyon's rim as of Sunday night, and officials Sunday said the fire had started spreading into the canyon itself.

Grand Canyon National Park's North Rim is closed for the remainder of the 2025 season due to a wildfire that has destroyed the historic Grand Canyon Lodge, cabins and visitors center. Here's what do know if you have a trip planned.
