Depending on the weather, it looks like Yellowstone National Park will close this year on November 2, 2009, with all park roads closed to the public at 8 a.m. except from the North Entrance to Upper Mammoth Terrace, and Mammoth via Tower Junction to Northeast Entrance. Cooke City via Colter Pass to the Long Lake gate is not maintained for wheeled vehicle travel.
