Crews toiling to plow roads in Yellowstone

YELLOWSTONE NATIONAL PARK, Wyo. (AP) — Two bulldozers have broken down since crews began clearing the heavy snowpack off Yellowstone National Park roads this spring.

The park has rented two machines as replacements in an attempt to clear roads from Mammoth to the West Entrance and south to Old Faithful by opening day March 2.

Yellowstone spokesman Al Nash says this winter stands out as the snowiest in recent memory.

Though cumulative snowfall amounts parkwide aren't immediately available, Nash says that, during the month of March alone, the park's South Entrance received 101 inches.

Nash says the snow is so deep in some places that the bulldozer operators have to push the snow off the roadway in layers to feed it to rotary plows that then blow it off the road surface.
