Firefighters continue Thursday to fight a 50-acre grass fire near Cheyenne Mountain State Park, the Colorado Springs Fire Department said.
Firefighters battled the blaze through the night after it was reported about 9 p.m. Wednesday near Norad Road and Colorado 115, across from Fort Carson.
The department requested a bulldozer, an air tanker and a helicopter to help fight the fire amid Thursday's red-flag conditions, when gusty winds and low relative humidity could cause the fire to spread quickly.
Due to the high winds, the helicopter and air tanker were grounded, said Captain Mike Smaldino.
Investigators arrived Thursday morning to search for what may have caused the fire, which burned in a "steep and rugged" area near the park, Smaldino said. Fifty firefighters were also on the scene, using hand tools to fight the fire, since the fire trucks were unable to get to the blaze.
The park is closed as fire crews continue to put out hot spots, Colorado Parks and Wildlife said in a tweet Thursday morning.
No structures were threatened, but two campers were evacuated Wednesday night and cattle from an adjacent ranch were evacuated Thursday morning, according to the tweet.
