CODY, Wyo. – Yellowstone Superintendent Suzanne Lewis says her staff are preparing for a normal winter season despite a court ruling against snowmobiling in the park.

Lewis told the Cody Chamber of Commerce on Monday that fuel storage tanks are being filled and poles are going up to mark snowmobile routes in Yellowstone.

A federal judge in Washington, D.C., rejected the park's winter use plan a couple weeks ago, saying wildlife could be harmed by the noise and air pollution from snowmobiles.

Lewis says she's been working with advisers and attorneys since the ruling to figure out what the legal options are for allowing snowmobiles in Yellowstone. Lewis isn't speculating on possible solutions and says she's unsure how the issue may be resolved.
