Oregon State Police say the weekend tour bus crash that killed nine people happened near a treacherous eastern Oregon section of road known as Deadman Pass.
Lt. Greg Hastings says the bus crashed along the west end of the Blue Mountains on Sunday after careening off an icy Interstate 84 and down a steep embankment. More than 20 people were injured.
The crash site is west of Deadman Pass, an area so dangerous the state transportation department published specific warnings for truck drivers. The state advises the area has "some of the most changeable and severe weather conditions in the Northwest" and can lead to slick conditions and poor visibility.
State police said the bus was en route from Las Vegas to Vancouver.
