LEHIGH TWP., Pa. - A fire has now spread to more than 250 acres in a popular Carbon County hiking spot.

As of Thursday morning, the fire at Lehigh Gorge State Park was estimated to be about 60% contained, according to officials with the Pennsylvania Bureau of Forestry.

Dozens of firefighters remained on scene Thursday. Close to 20 fire crews have been helping fight the flames since the fire broke out around 1 p.m. Wednesday.

Putting out the fire has been difficult. Tankers have been making trips to the Lehigh River to fill up with water. Crews also have to travel about three miles into the forest from the staging area to get to the blaze.

No injuries have been reported, officials said.

Authorities have not said how the fire started, but a firefighter on scene Wednesday said a crew of workers was grinding railroad tracks in the area and may have sparked the blaze. The workers tried putting out the fire themselves before calling 911, the firefighter said.

In addition to fire departments, members of the state's Department of Conservation and Natural Resources and its Bureau of Forestry are also on scene.
