Two roads in Grand Teton National Park are set to close to vehicle traffic for the season Halloween night. These seasonal closures include the length of the Teton Park Road between Taggart Lake parking area and Signal Mountain Lodge parking lot, as well as the Moose-Wilson Road between Granite Canyon and Death Canyon trailheads. Spokesperson Jackie Skaggs adds that the Moose, Moran and Granite Canyon entrance stations will be temporarily closed for the month of November and early December. They will reopen December 15th for the winter season. Skaggs adds that for the first year, the Craig Thomas Discovery and Visitor Center in Moose will close for the winter season as well beginning Monday. Skaggs says, “One of the things we looked at among many things was the cost of running the Discovery Center during a time when we have the least amount of visitors.” She says the winter months are the lowest visitation time and it is a very costly building to run when you consider heating and plowing the roads and walkways around it. Then, she says there is the consideration of staffing the building with NPS personnel. Skaggs says a cost/benefit analysis will be done at the conclusion of this winter closure to determine a course of action for future years. In addition to road closures in Grand Teton National Park, the Grassy Lake Road in the John D. Rockefeller, Jr. Memorial Parkway closed for the season with todays snowstorm.
