(WEST YELLOWSTONE, MT) – Yellowstone National Park has released its 2014-2015 winter use plan. The policies, which will not be in effect for the upcoming season, will eliminate many restrictions on snowmobiles and snow coaches currently in place. The plan allows for up to 50 groups of ten snowmobiles each day. All snowmobiles will have to be fitted with new pollution-controlling exhaust systems by 2015, and snow coaches will have to have similar controls in place by 2016.
