A wildfire burning four miles north of Flagstaff is fully contained after charring more than 15,000 acres.

U.S. Forest Service officials say the so-called Schultz Fire has burned an estimated 15,075 acres, or more than 23 square miles of scenic northern Arizona forest. It has cost more than $8.6 million to fight.

The blaze was started June 20 by a campfire that was abandoned without being properly extinguished in the area of Schultz Tank, Little Elden Trail and Forest Road 420. The Forest Service is offering a reward of up to $2,500 for information leading to the arrest and conviction of those responsible.
