Coronado National Forest officials said crews are dealing with four new wildfires on forest lands in Southern Arizona.
All started on Tuesday, with three being caused by lightning and one is considered human caused, according to a news release from the forest.
The new fires burning are:
Mule Ridge Fire
The human-caused fire is burning in oak grassland north of the Pajarita Wilderness boundary near Ruby, southeast of Arivaca.
It is about 600 acres and zero percent contained.
No structures are threatened but the historic mining settlement of Ruby is about 1½ miles northwest of the fire.
There are 110 firefighters assigned to this fire, along with three helicopters, 2 single-engine air tankers and an air-attack fixed-winged airplane.
Portal Peak Fire
The fire is burning near Portal Peak and was caused by lightning.
It is about 300 acres and zero percent contained.
About 45 people are assigned to the fire, including five engines, one water tender and two single-engine air tankers.
The fire is burning in an area already burned during the Horseshoe 2 Fire in 2011.
Jhus Canyon Fire
The fire has burned about 20 acres in the Chiricahua Mountains west of Portal. There are 40 people assigned to the fire. The blaze is burning in brush and grass.
Full containment is expected in 24 hours.
Whitetail Canyon Fire
The wildfire is burning north of Chiricahua National Monument, southeast of Dos Cabezas and is about 95 acres. It was strated by lightning and is zero percent contained.
The fire is being monitored by crews but is showing light fire activity.
