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 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 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.
