PHOENIX (AP) -- Crews fighting a 1,300-acre wildfire in southern Arizona focused Tuesday on extending a protection line around the blaze.
The fire near Red Mountain, about four miles south of Patagonia, was 40 percent contained and expected to be declared fully contained by Friday evening.
People living in 15 houses in the fire's path had been voluntarily evacuated earlier but were allowed to return home Sunday night.
Utilities also restored electric power service to about 100 homes. Their power had been turned off as precaution.
Portions of the Aztec fire burned in steep, rocky terrain and in narrow canyons, making it difficult for firefighters to attack the blaze in the Coronado National Forest.
The fire was first spotted Saturday afternoon and caused by an abandoned campfire.
Four hundred sixty people and three helicopters were fighting the blaze.
