Representatives of Yellowstone National Park last night provided anyone in Jackson interested in the redrafting of a winter use plan, the opportunity to view proposed revisions and provide additional input on the seven alternatives to be proposed. As yet, there is no preferred alternative. Yellowstone Superintendent Dan Wenk says the revisions come as a result of input received last year during public hearings on the proposed final winter plan. One of the new proposals involves determining the amount of winter travel in the park by virtue of the sound impacts of the vehicles rather than setting a number of vehicles. Wenk explains that this is a supplemental environmental impact statement so that the revisions will amend the work previously done. A draft supplemental plan is to be released in late April.
