Authorities at Rocky Mountain National Park are investigating an alleged attack.
A 20-year-old woman reported the attack Saturday. She said she had been running and was attacked by a man while taking a break near the Glacier Creek Trail.
She was able to fight him off and ran down the trail to call for help.
It happened about a half mile from the Glacier Basin Campground.
Park spokeswoman Kyle Patterson said rangers have increased patrols in the area.
