On July 14, 2015, at around 11:15PM, OSP Troopers and emergency personnel responded to HWY 46 (Caves Highway) near milepost 6 on the report of a rollover serious injury crash. According to Sergeant Jeff Proulx, a 1990 Toyota 4runner was eastbound on HWY 46 when it left the roadway and struck a large tree. The operator, Dalton H BROWN, age 24, of Grants Pass was pronounced deceased upon emergency crews arriving on scene. Initial investigation appears speed may have been a factor. OSP was assisted by the Illinois Valley Fire Department, American Medical Response and the Oregon Department of Transportation.
