Two weeks after Yellowstone opened for the winter season, enough snow has fallen to allow snowmobile and snow coach travel.

Snow vehicles were allowed in the national park starting Saturday.

Only wheeled and rubber-tracked vehicles had been allowed on park roads since the Dec. 15 winter opening, but enough snow fell in the last week of December to allow steel-tracked machines.

The road between Mammoth Hot Springs is still restricted to rubber-tracked snow coaches until more snow falls.
