Hayden A fire destroyed a Chevrolet Blazer west of Hayden on Friday morning.
West Routt Fire Protection District Chief Bryan Rickman said a passing motorist spotted the burning sports utility vehicle at around 8:50 a.m. about two miles west of Hayden on U.S. Highway 40.
There was no one around the vehicle when Colorado State Patrol troopers and West Routt firefighters arrived, Rickman said.
"It took us about 30 minutes to fully contain it," he said. "It was a pretty good fire."
The fire is being investigated as arson, he said.
Officers are still in the process of finding out who owns the vehicle, he said.
"At this point we have no idea who this car belongs to," he said. "No one saw anyone near the car."
A license plate was found, though it was covered in stickers that had burned in the fire, Rickman said.
He did not think it was a Colorado plate.
Rickman said it was difficult to determine if someone had used any accelerants, such as gasoline, to start the fire because it appears the fire started near the rear of the vehicle near the fuel tank, he said.
