Crews on Thursday were battling a 95-acre blaze burning west of Gallinas near Evergreen Valley.
The Middleton fire was 38 percent contained as of Thursday morning. Santa Fe National Forest officials believe it was started by a downed power line.
“This is an early warning sign,” said Lawrence Lujan, a spokesman with the forest service.
He said the dry winter has increased the fire danger, and people need to be careful because conditions exist for a big fire.
