TUCSON, AZ — State and local crews have completely contained the Biosphere Fire at 13 acres Sunday.
The fire is a half mile southwest of the Biosphere and northeast of the Oracle Junction.
Arizona State Forestry, Golder Ranch Fire District, and Northwest Fire District worked to maintain the fire.
The fire is visible to Oracle and the surrounding areas, but there are no evacuations at this time.
State Forestry launched aircraft, including Single Engine Air Tankers and Air Attack platform to assist with suppression.
The cause of the fire has not yet been determined.
Officials say a rancher in the area noticed smoke Sunday morning and notified Biosphere 2 employees, who then called 911.
No structures were damaged or destroyed.
