Firefighters from Reading and the surrounding suburbs battled a wind-driven brush fire on Mount Penn Thursday afternoon.
Crews got the call around 2 p.m. for a fire in the area near Richmond Street and Oak Lane.
Initial reports from city firefighters on the scene were that the fire was slow-moving and about 5,000 square-feet in size, but stronger winds quickly caused the fire to spread, covering as many as 10 acres of land on the mountain.
A tall column of smoke could be seen from as far away as the Broadcasting Square shopping center in Spring Township.
The Berks Emergency Strike Team, along with crews from as far away as Ruscombmanor Township and Gibraltar, worked the ground as a plane drops water from above.
Their efforts to stop and extinguish the fire were hampered by dry conditions on the mountain, officials said.
One firefighter was overcome by smoke and treated by paramedics on the scene. There have been no reports of other injuries.
