Strong winds and hot, dry weather continue to fuel two separate wildfires near the northwestern side of the Grand Canyon Saturday, closing the canyon’s North Rim and forcing evacuations throughout the area.

Hundreds of visitors and residents were evacuated from the North Rim of Grand Canyon National Park this week as two wildfires advanced toward the park.

Visitors and staff at two national parks in the U.S. West have been evacuted because of wildfires. Officials at Black Canyon of the Gunnison National Park in Colorado say the park closed Thursday morning after lightning sparked blazes on both rims.
