March 1 means two things in Yellowstone: a celebration of the birth of the world’s first national park in 1872, and the beginning of the end of motorized oversnow travel in the park’s interior for another year.
Commercially guided snowmobile and snowcoach travel between Fishing Bridge and the park’s East Entrance over Sylvan Pass ends at 9:00 p.m. on Thursday, March 1. Closures on other road segments will occur during the next two weeks, with all oversnow travel scheduled to end for the season at 9:00 p.m. Thursday, March 15.
Once the roads close to oversnow travel, crews will begin to clear them of snow so they can reopen to automobile travel in the spring, beginning Friday, April 20, weather permitting.

The NPS intends to have a final Supplemental EIS, a Record of Decision, and a long-term regulation for winter use in Yellowstone in place before the mid-December start of the 2012-2013 winter season.
