YELLOWSTONE NATIONAL PARK, Wyo. (AP) — Yellowstone National Park's East Entrance is expected to open to the public for the winter season today.

Park officials say rubber-tracked snowcoaches and snowmobiles will be allowed to travel between the entrance through Sylvan Pass to Fishing Bridge and West Thumb. But steel-tracked vehicles will not be allowed on the route until more snow accumulates on the roads.

The park has recently opened several routes for limited, commercially guided snowmobile and snowcoach travel.

One park road will remain open to regular vehicle travel during the winter. It runs from the north entrance at Gardiner, Mont., through Mammoth Hot Springs, Tower Junction and the Lamar Valley to Silver Gate and Cooke City, Mont.
