Firefighting crews are still

battling to contain the Mines Spung Wildfire

in Burlington County Monday, officials said.

An update from the New Jersey Forest Fire Service Monday morning said the blaze in Wharton State Forest in Shamong Township remains at 5,750 acres and is still 80% contained.

An observation flight will be conducted over the fire as soon as weather conditions allow, the agency said.

Lower Forge Campground remains evacuated and five structures are still threatened by the fire, officials said.

Several roads remain closed Monday including Tuckerton Road from Carranza Road to Washington Turnpike and Carranza Road between Forked Neck Road to Tuckerton Road, officials said.

The Batona Trail between Carranza Road and Quaker Bridge Road remains closed as well, according to the Forest Fire Service.

The

Mines Spung Wildfire broke out Friday afternoon

and quickly grew to over 400 acres and caused several evacuations.

By 11 p.m. Friday night, the

fire had grown to over 3,250 acres

and was only 35% contained.

The Lower Forge Campground was evacuated and roads around Wharton State Forest were closed as crews fought to contain the fire.

Phillip M. Costello Preparatory Academy

, a school under New Jersey’s Juvenile Justice Commission serving 15 to 20-year-olds with a history of substance abuse, was also evacuated Friday as a result of the fire, authorities said.

By Saturday night the

fire was 75% contained

but had ballooned to over 5,500 acres.

The cause of the fire is still unknown and remains under investigation, according to officials. No injuries have been reported as a result of the fire, authorities said.

The Mines Spung Wildfire is the largest wildfire in New Jersey since the

Jones Road Wildfire in Ocean County

burned over 15,000 acres in April.

The Forest Fire Service said the next update on the status of the fire would be provided on Tuesday at 12:30 p.m.
