ROCK SPRINGS, Wyo. — One person is dead and another injured in a single-vehicle crash Monday afternoon in Sweetwater County.

According to the Wyoming Highway Patrol, the driver of a Nissan Pathfinder was westbound on Interstate 80 near milepost 124.70, when they failed to negotiate a slight left curve in the roadway. The vehicle appears to have driven straight off the roadway, where it collided head-on with a rock cliff face. The vehicle traveled up the cliff face in a side-swipe motion about 6 feet before rolling several times down the shoulder.

Killed in the incident was 72-year-old Utah resident Dahlin Ackerman, who was a passenger in the SUV.
