Yellowstone National Park Crews continue their efforts to Open Dunraven Pass and Beartooth Highway for the season. Spring clearing of the Beartooth Highway will resume Monday following a week-long cleanup and safety assessment of a rock slide that temporarily closed the road between Mammoth Hot Springs and Tower Junction. That road reopened June 1st.
Because the May 28th slide cut off the northeast corner of Yellowstone from the rest of the park, crews simultaneously went to work clearing the road between Tower Junction and Canyon Village over Dunraven Pass to open a secondary route to the Lamar Valley and restore park access for the residents of Cooke City and Silver Gate, Montana.
Like Sylvan Pass, its neighboring high route to the south, Dunraven Pass has proven to be not without its own spring clearing difficulties. After clearing two lanes of the 18-mile long high elevation road, crews unexpectedly discovered a layer of thick ice covering several miles of the road surface. A few more sunny, warm days will be needed to weaken the exposed ice layers before plows can successfully peel it off the asphalt.
Unstable snow conditions and the threat of snow slides currently limit travel on the East Entrance road through Sylvan Pass to between the hours of 8:00 p.m. and 10:00 a.m. Current and forecast weather conditions indicated this limited travel window will remain in place at least for several more days. The North, West, and South entrances to Yellowstone are open, subject to temporary closures due to weather. Information on park road conditions is available 24 hours a day by calling the park’s road information hotline at 307-344-2117.
