The Caribou-Targhee National Forest winter travel regulations for the Teton Basin Ranger District have gone into effect now. Caribou-Targhee Spokesman Lynn Ballard says the official travel map for the Teton Basin Ranger District describes winter travel opportunities for both winter cross-country use, and winter designated routes. This map along with the snow machine map produced by the Idaho State Parks and Recreation shows winter recreationalists groomed cross-country ski trails and snow machine trails, areas with seasonal closures, and areas closed to protect wildlife winter range or designated Wilderness. Ballard says maps and additional information may be obtained through the Teton Basin or adjacent Ranger Districts. Unless designated or authorized, roads maintained by Fremont, Madison, Teton Counties, and plowed public roadways through state and federal lands are not open to snow machine use. Additionally, Ballard emphasizes that the Jedediah Smith Wilderness is closed to snow machine use at all times. Users recreating near winter range and wilderness areas should note that entering one of these areas is a violation of Federal Regulation and subject to fines up to $5,000.00 and or six months in jail.
