American Airlines says one of its jets went past the end of the runway while landing at Wyoming's Jackson Hole Airport, but no one was injured and the plane appears undamaged.
Airline spokesman Ed Martelle says Flight 2253 from Chicago "had a long rollout" when it landed shortly before noon Wednesday. The plane came to rest on a hard surface and did not go off into grass or brush.
There were 175 passengers, two pilots and four flight attendants on board the Boeing 757.
Officials are trying to determine why the plane couldn't stop sooner.
Janice Altman, who lives near the airport, says the plane came to rest in an area of deep snow.
The National Weather Service reports Jackson Hole has received up to 7 inches of snow since midnight.
