Someone rolled a Chevy TrailBlazer down a mountainside in the rugged Guardsman Pass area south of Park City early Monday morning, the authorities said, dramatically ditching the sport utility vehicle as the owner, a Salt Lake City woman, reported it stolen.

The white Trailblazer was found right-side up at the bottom of a steep, rocky slope off the Guardsman Pass road that connects Park City with Big Cottonwood Canyon. It stopped between 300 and 500 feet below the road, close to a stand of trees. It was found in Wasatch County, about 200 yards from the Salt Lake County line.

Investigators said nobody was inside the vehicle when it went off the road. A medical helicopter and law enforcement officers searched the surrounding terrain for victims, but they did not find anybody injured in the wreck.

Travis Jensen, a Wasatch County Sheriff’s Office deputy who responded, said the authorities received a report of the vehicle at 6:06 a.m. from a passing driver. He said the Trailblazer rolled at least one time before it came to rest. No blood was found to indicate somebody was inside when it crashed.

Jensen said it appears the vehicle was intentionally pushed off the edge of the road.

“There was nobody at the scene. There were no witnesses,” Jensen said.

The Salt Lake County Sheriff’s Office said the TrailBlazer was reported stolen in Salt Lake City Monday morning, at about the same time it was discovered. Don Hutson, a lieutenant in the Salt Lake County Sheriff’s Office, said the vehicle was in the driveway when the owner went to bed at 2:30 a.m. The person woke up and found that it had been stolen sometime before 6:30 a.m., he said.

Hutson said it appears the person who stole the vehicle immediately drove to Guardsman Pass. He said there is not evidence that the person used the TrailBlazer to commit a crime before ditching it in the mountains. Hutson said the person who took the car did not steal anything from the inside. He said the stereo and personal items were left in the TrailBlazer.

He said it appears someone pushed the TrailBlazer off the edge at a “very low speed.”

“How that occurred or why, I don’t know if we’ll ever know the specifics,” Hutson said.

Police officers, sheriff’s deputies, firefighters and tow-truck operators responded to the scene, forcing the closure of a small section of the Guardsman Pass road until the middle of the afternoon.

The high-altitude road, which is unpaved and rocky for a stretch between Park City and Big Cottonwood Canyon, is a scenic route perched on the mountainside. There are not guardrails, and the road is typically closed from the fall until the spring or early summer. There is little traffic on the road. Summit, Wasatch and Salt Lake counties converge in the area close to Guardsman Pass.

Tow-truck operators called to recover the TrailBlazer faced difficulties, and they had to call for a bigger truck to pull the vehicle back onto the road. Three tow trucks were sent to the scene.

At just after 9 a.m., Joe Cole, a driver for Park City Towing who responded, rappelled down the rocky slope to hook the TrailBlazer to a tow line, but the line did not hold. Later in the day, the crew was successful in attaching a line to the vehicle.

Brad Belcher, the office manager at the towing company, said his workers got the TrailBlazer out at a little before 3 p.m. His crews are trained to recover vehicles from steep slopes, but the operations are difficult, requiring them to pull the vehicle up a little bit and reset the line repeatedly, Belcher said.

“Time consuming. You’re having to pull it up easily,” Belcher said.
