One man died in a two-vehicle accident on Thursday afternoon at the intersection of Highways 97 and 197 in southern Wasco County. The Oregon State Police reports its preliminary investigation indicated a northbound pickup truck driven by 81-year-old Frank Lee Serfoss of Ronan, Montana, was pulling a single axle utility trailer and crossed over the paved center median into the southbound lanes. The pickup crashed head-on into a southbound semi-tractor pulling a flatbed operated by 30-year-old Christopher Michael Dalton of Clifton, Arizona. The OSP says Serfoss was declared deceased at the scene, while Dalton sustained non-life-threatening injuries and was treated, but was not transported to a hospital. The cause of the crash is still under investigation. The OSP was assisted by Jefferson County Fire and EMS, South Wasco Fire and Rescue, Life Flight, and ODOT.
