New Mexico ? Firefighters worked in cooler, calmer weather Saturday to clear lines around a blaze that has burned nearly 60 homes and more than 20 square miles in the mountains of central New Mexico.

Authorities were able to confirm Saturday that 50 homes burned Wednesday in a fire caused by humans in the Manzano Mountains, southeast of Albuquerque, said Linda Peters, a fire information officer. Nine homes had burned earlier.

The 50 homes went up Wednesday after the fire jumped containment lines.
