A fire on Saturday evening destroyed four Eastford, Connecticut buildings owned by the Yale School of Forestry and Environmental Studies.

The buildings, tucked away in a densely wooded area 70 miles northeast of New Haven, functioned as forestry training sites for Yale students. While the cause of the  fire is currently unknown, fire officials said state and local officials are investigating the incident.

The blaze, which was reported to authorities after 7 p.m. Saturday, was brought under control by 9:30 p.m. With the flames largely quelled, firefighters scoured the rubble to fully extinguish the fire, Fire Chief Gordon Spink told the Harford Courant.

“It’s a total loss,” Spink said.

No injuries were reported following the fire, which challenged firefighters due to its remote location. Yale’s buildings sat a half-mile off Center Pike Road, which impeded the firetrucks.

The burnt buildings had arched metal roofs and strong interior timer, Spink said. The 7,800 acres of the Yale Myers Forest are located in the northeast corner of the state.

More than 12 fire departments from nearby towns converged on the forest to combat the blaze.
