Firefighters are getting closer to taming a wildfire burning across the New Jersey-New York border, increasing their encirclement of the hard-to-access blaze.

The Jennings Creek wildfire has burned roughly 5,201 acres, and the New York State Department of Environmental Conservation (DEC) said 12% has yet to be contained. The New York Air National Guard continued bucket drops on the wildfire on Saturday.

The Jennings Creek wildfire is now 88% contained since it started burning last week, the New York State DEC said.
