Authorities are making progress as they battle a wildfire that broke out in New Jersey’s Passaic County earlier this week, chewing through 160 acres in a matter of hours as firefighters fought to douse the flames. New Jersey’s Forest Fire Service said Thursday that the so-called Buckabear Wildfire in West Milford Township was 50% contained, a marked improvement from their announcement the previous evening. The 160-acre fire hadn’t grown, acre-wise anyway, since the last announcement either. As of Thursday, no evacuations had been ordered and no structures are threatened. …Firefighting efforts intensified in earnest Wednesday, with a state Forest Fire helicopter dumping water onto the remote wooded area to halt the spread. Deep inside the forest, other crews were armed with shovels, garden hoes and specialized ignition devices — deliberately igniting the dry brush on fire in a controlled burn, They literally fought fire with fire.
