Laramie, WY – A federal judge has upheld the National Park Service's decision banning the use of snowplanes at Jackson Lake.
US Judge William Downes last week rejected arguments from a group called Save our Snowplanes that sued the Park Service two years ago.
The group claimed that the federal agency had failed to provide a reasoned analysis of its decision to ban the vehicles from the lake.
Snowplanes are propeller-driven machines that ice fishermen have used for decades to move around the lake in wintertime. The Park Service decided that they should not be allowed because they're too loud.
Downes ruled that snowplane supporters failed to show any evidence that the Park Service was wrong in its analysis.
