Rapid growth on the South Rim fire in Black Canyon of the Gunnison National Park forced immediate evacuations in Montrose County on Saturday afternoon.

A fire near the Grand Canyon National Park in Arizona has grown more than 20 times in size in 24 hours as an intensifying wildfire season sees the return of Canadian wildfire smoke into the U.S.

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.

The Grand Canyon’s North Rim in Arizona also closed Thursday because of a wildfire on adjacent Bureau of Land Management land near Jacob Lake. The Coconino County Sheriff’s Office said it helped evacuate people from an area north of Jacob Lake and campers in the Kaibab National Forest nearby.

A man was killed and a woman seriously injured Friday night when a speeding sports car went airborne and rolled several times off a rural stretch of state Highway 12 in Napa County, the California Highway Patrol said.

A 63-year-old woman was found a quarter mile away from her vehicle. The investigation indicated she was returning to the trailhead when she collapsed.

The woman who was found dead in Cedar Canyon on the evening of June 27 has been identified, according to the Iron County Sheriff's Office.
