Laramie, Wy – A mudslide caused by torrential rain trapped 16 people in their vehicles in Yellowstone National Park Sunday.
Spokesman Al Nash says no one's been injured.
Workers were trying to free three vehicles from the mess, which has temporarily closed the park's east entrance.
Nash says the slide occurred around eight p-m Sunday.
As much as four feet of mud covers the east entrance road from Cub Creek to an area about seven miles from the park's eastern boundary.
