HAPPY JACK, AZ (CBS5/AP) -

Firefighters working to contain a wildfire burning in northern Arizona have seen the fire quickly grow to 1,250 acres.

The Jack Fire was reported around 11:40 a.m. Saturday, when it was at around 80 acres. 

Spokeswoman Heather Noel said no structures are threatened.

The fire is burning about 13 miles northeast of Happy Jack in a canyon. It's burning mostly grass and pinyon-juniper toward State Route 87.

At least 120 firefighters are working to control the blaze.

Noel says aerial tankers are focusing on the left side of the fire and two Hot Shots crews and 90 firefighters are on its right flank.

The cause of the fire is still unknown.
