Two drivers were seriously injured in a head-on crash in Happy Valley Thursday morning. A little before 8:30AM a Chevy Tahoe was heading up the China Gulch Hill from Canyon Road while a big Chevy dually was heading downhill. Women were driving alone in both vehicles. They met on a curve and one of them crossed over the center line. They hit each other’s driver’s side corners and the Tahoe tumbled about 40 feet over the edge to the bottom of the canyon. That driver was trapped. Both women suffered major injuries.
