PORTLAND, OR (KATU/CNN) - Authorities believe they know what sparked a 3,000-acre wildfire in Oregon.
The fire has led to the evacuation of dozens of homes near the town of Cascade Locks.
The Eagle Creek fire spread across the area overnight.
"Had we doddled 20 minutes longer, we probably would've been stuck there," said hiker Kevin Marnell.
Marnell and his friends barely got off the Eagle Creek trail Saturday afternoon.
"We hear this shotgun blast, well it sounded like a shotgun, something loud, big bang," he said.
They didn't think anything of it until they saw the smoke.
At the trailhead, Kevin recorded what looked like an interaction between three teens and an Oregon State Police officer.
"There was a police officer, there were two boys sitting down on the side of the road," Marnell said.
Oregon State Police later suggested fireworks may be to blame.
"It's believed to be one suspect," said Sgt. Jason Collway. "He has been identified and is cooperating with the investigation."
The suspect has been cooperating with police and has not yet been charged with a crime.
More than 130 homes have been evacuated due to the wildfire.
