The giant boulders fell from a hillside that has endured pounding rain and repeated freezing and thawing of the rock due to harsh winter conditions, said Gary Leaming, a spokesman for the Oregon Department of Transportation. The driver of the Toyota SUV came around a curve on the windy and rural highway near Prospect, Oregon and swerved to miss the first boulder, but crashed into the second. "They got out to survey (the damage) and more came down and some might have struck them," he said, adding that one and possibly both passengers had been taken to a hospital but were expected to survive.
