SAN MATEO, N.M. – A wildfire in Cibola National Forest continues to grow as about 130 firefighters work to fight the inferno.

New Mexico and federal fire officials said late Tuesday the blaze has swelled to 8 square miles and is about 28% contained.

Recent rains have created favorable conditions, allowing fire managers from the Cibola National Forest and National Grasslands to manage the wildfire near an inactive stratovolcano in the San Mateo Mountains.

Officials say the fire was caused by lightning on Aug. 4. It’s located about 100 miles west of Albuquerque.
