The Silver Gate area is famous for excellent snowmobiling. There are over 60 miles of groomed trails in the Gallatin National Forest. The Cooke City trail system also connects with 50 miles of groomed trails in Wyoming. Cooke City can be accessed only through Yellow-stone's Mammoth entrance at Gardiner in the winter. Access to the Northeast Gate from Cody is closed to vehicular traffic because of heavy snow over the passes. The season runs Thanksgiving through mid-May. There is a shuttle service between Mammoth and Cooke City. 

Archaeology lovers will be intrigued by the "Grasshopper Glacier." The glacier has dark bands of grasshoppers that have been frozen within the Ice for centuries. The migrating grasshoppers were caught in one of the harsh storms relatively common to the high-altitude area. Usually about August, enough snow has melted away that the dark band is visible. If you're pulling a high-clearance 4-wheel drive vehicle (necessary even to begin the journey up LuLu Pass-Goose Lake Road), then consider putting the side trip on your itinerary. You need to make a very strenuous hike to get to the glacier; don't attempt this climb unless you're in great shape, and do not even think about driving your RV in here.
