Firefighters have been busy on Mt. Lemmon Friday, working to contain the Molino 3 Wildfire, with broke out in Molino Basin Thursday early evening.

This afternoon the Forest Service adjusted the size of the fire from 1000 acres to 425 acres after special plane conducted dozens of flyovers, making more precise measurements than what was available earlier.

The fire itself has been hard to see, as it’s nestled in the Molino Basin's bowl-shaped area, blocking the view in most directions. What KGUN 9's cameras could see throughout the day were the several fire retardant drops by plane into the affected area.

“It's very rugged terrain, lots of deep crevasses," U.S. Forest Service spokesperson Starr Farrell told us.

"So it's not somewhere that you're gonna go out and go for a leisurely hike. Now we do have some trails that are closed down, just because the possibility of interaction with firefighters moving in and out of the area, or potential for that fire to spread into it. So there are some closures and those are listed on our Facebook page and on our Coronado National Forest website.”

For those curious about going up the mountain to see the fire, the Forest Service is discouraging people from making the trip up the Mt. Lemmon Highway for fear they may interfere with emergency vehicles.

And while trips are discouraged, the road itself remains open. People who do need to drive the Mt. Lemmon Highway can call the road closure hotline for updates at (520) 547-7510.

As of Friday evening, the following trails are closed through Friday, Sept. 15:

  • Babad Do’ag Trail #705,
  • Molino Basin Trail #11,
  • Soldier Trail #706

The recreational shooting area along the highway is also closed, reports Coronado National Forest.

The cause of the fire is still under investigation.
