Measurable snow has fallen around much of Wyoming in the past couple days, creating hazardous driving conditions, closing Teton Pass off and on, even causing closures along I-80 because of winter driving conditions. It comes as no surprise then that travel in Yellowstone National Park has become tentative for the last couple weeks roads areopen to wheeled vehicles there. Spokesman Dan Hottle says visitors to the park need to be ready for about anything. Hottle says visitors may find changing conditions could prohibit them from leaving the park through the entrance they had planned, and so they need to keep their plans flexible. Hottle adds that travelers should have their vehicles outfitted for winter driving including extra clothes and emergency kits to help them if they become stranded. Hottle says snowfall has varied with some substantial measurements around the interior of the park. He says measurements have been as deep as eight, ten, and even twelve inches in some interior areas of the park . Total closure of Yellowstone’s interior roads for the season is scheduled for November 5th.
