North Cheyenne Canyon Park, including Helen Hunt Falls, closed for the day as Colorado Springs firefighters put out a fire on Mount Muscoco that was discovered early Saturday morning.
The Four Corners fire was reported at about 1:45 a.m. in the Cheyenne Canyon area and was less than one acre but in steep and rocky terrain, according to the Colorado Springs Fire Department. Helicopters assisted crews with "water bucket drops" to put the fire out.
No evacuations were ordered but roads into Cheyenne Canyon closed, officials said.
The fire was under control by Saturday evening and will continue to be monitored throughout the night and Sunday.
