Winter Use Rule Published in Federal Register

November 17, 2009
Superintendent Mary Gibson Scott announced today that the rule implementing the winter use plan for Grand Teton National Park and the John D. Rockefeller, Jr. Memorial Parkway will be published in the Federal Register on Friday, November 20, 2009. The winter use plan allows snowmobile access for the purpose of ice fishing only on the frozen surface of Jackson Lake, and allows snowmobiles to use the Grassy Lake Road between Flagg Ranch Resort and the Caribou-Targhee National Forest. On Jackson Lake, snowmobiles must meet National Park Service air and sound emissions requirements for Best Available Technology (BAT). The requirement does not apply to snowmobile use on the Grassy Lake Road.

The published rule will implement a Finding of No Significant Impact (FONSI) signed last month by National Park Service Intermountain Region Director Mike Snyder. The FONSI and the winter use environmental assessment are available online at, and the winter use rule will be available at

Highway 26/89/191 from Jackson, Wyoming to Flagg Ranch Resort in the John D. Rockefeller, Jr. Memorial Parkway is open and plowed for wheeled vehicles throughout the winter season. This road provides access to a wide range of recreational opportunities including wildlife viewing, cross-country skiing, snowshoeing and ice fishing. The Teton Park Road is closed to vehicle traffic during the winter season from Taggart Lake parking area to Signal Mountain Lodge—a distance of fifteen miles. The unplowed roadway is groomed and serves as a winter trail for cross-country skiing, skate skiing and snowshoeing.

The Craig Thomas Discovery and Visitor Center near park headquarters at Moose, Wyoming is open year-round and offers ranger-led snowshoe hikes each day from December 26 through late March.
