Sheriff's deputies said a person was hurt riding an ATV while camping with a group southeast of Silverton on Memorial Day weekend.
Three campers were taking the injured ATV rider to the hospital in a car early Saturday morning when officials said the driver lost control, went off of Grade Road near the intersection of Bridge Creek Road and rolled down an embankment.
The car came to a stop on its top. The driver and two passengers managed to get out of the car, but the injured ATV rider was trapped inside the vehicle.
Emergency dispatchers received a call about the crash at around 3:20 a.m. Saturday. The Marion County Dispatch Center used the caller's cell phone and GPS technology to trace the call to Grade Road.
Fire crews pulled the trapped person from the rolled car. The injured person was then flown by air ambulance to Salem Hospital by a Lifeflight helicopter.
Officials say it appears most if not all of the person's injuries were caused by the ATV crash and not the car crash.
The Marion County Sheriff's Office is looking into the ATV crash. Deputies checked the group's campsite and found it had been deserted.
Grade Road was closed for over four hours while crews looked into the crash.
Deputies haven't issued citations or made any arrests, but said the investigation is ongoing. Anyone with more information is asked to call Deputy Mark Ferron at 503-558-5032.
