Five wildfires are burning on thousands of acres in western Colorado, including one that crossed into the state from Utah, fire officials said Sunday.

The fires varied in size but have already forced several evacuations and pre-evacuation notices, closed a national park, and the Deer Creek Fire near the Utah state line has already destroyed at least five buildings.

The Deer Creek and South Rim fires are burning in Montrose County, with the South Rim Fire estimated at 3,500 acres as of Sunday morning. Black Canyon of the Gunnison National Park in southwestern Colorado is closed due to wildfires on both rims of the canyon.
