With snow already on the ground, Grand Teton National Park officials are getting ready to set out the "road closed" signs on the park's interior roads.

Road closures that will take effect Sunday night include the length of the Teton Park Road between Taggart Lake parking area and the Signal Mountain Lodge parking lot, as well as the Moose-Wilson Road between Granite Canyon and Death Canyon trailheads.

In addition to the annual road closures, the Moose, Moran and Granite Canyon entrance stations will temporarily close for the month of November and early December; they are scheduled to reopen on December 15 for the winter season, a park release noted.

The Craig Thomas Discovery and Visitor Center in Moose, Wyoming is open year-round; however, hours of operation for the winter season will be adjusted to 9 a.m. to 5 p.m. daily.

Annually, the Teton Park Road is not plowed after the first of November. During the time that the Teton Park Road remains free of snow, visitors are welcome to use the roadway for non-motorized recreation such as walking, bicycling, and in-line skating. Once the snow begins to accumulate on the roadbed, winter season activities such as cross-country skiing, skate skiing, and snow-shoeing become possible.

Pets are permitted on park roadways; however, pet owners are reminded that dogs must be leashed and under physical restraint at all times. Dog owners are required to clean-up their pet’s waste, and mutt mitt stations are provided for that purpose during the off season months.

In addition to road closures in Grand Teton National Park, the Grassy Lake Road within the John D. Rockefeller, Jr. Memorial Parkway will close for the winter season with the first major snowstorm.
