SANTA FE, N.M. — Firefighters are working to knock down a wildfire that broke out Friday about 5 miles northwest of Las Vegas, threatening some structures and causing students at nearby United World College to voluntarily evacuate. Leo Maestas, emergency manager for San Miguel County, said fire crews with the U.S. Forest Service, New Mexico Forestry and about four local crews were on the fire, which was reported about 1 p.m. A helicopter was also helping with fire suppression efforts, he said. What’s been named the Peterson Fire had burned about 20 acres on both side of N.M. 65 near the Peterson Reservoir by late Friday afternoon and had slowly crept east during the day.
