As of Tuesday morning, guided visitor travel in Yellowstone National Park between West Yellowstone and Old Faithful was limited to commercial snowcoaches with rubber tracks or commercial wheeled vehicles.
A long stretch of above-normal temperatures, limited snowfall and oversnow traffic have resulted in bare pavement along the route resulting in unsafe conditions for snowmobiles and snowcoaches with ski steering.
Despite the changing conditions, visitors may not use their private wheeled vehicles to travel into the park.
The park has worked with groups who had planned a guided snowmobile tour into the park originating from West Yellowstone, and has found ways for most, if not all, of them to travel into the interior of the park.
Conditions on all other interior park roads, which are groomed for commercial and noncommercial guided snowmobiles and commercial snowcoaches, remain fair to good.
Guided travel from West Yellowstone to Old Faithful will continue as scheduled through March 15.
