A section of road between Mammoth Hot Springs and Tower Junction in Yellowstone National Park reopened Wednesday afternoon after a rockslide last weekend closed the road to all but emergency travel. Park Spokesman Al Nash says park geologists and representatives of the Federal Highway Administration examined the slide area Tuesday and decided the route could be reopened after it is cleared. Meanwhile, Nash says crews are working on opening Dunraven Pass for the season; and that too may be open by this weekend. At this time, the North, West, and South entrances to Yellowstone are open, subject to temporary closures due to weather. Unstable snow conditions and the threat of snow slides continue to limit travel on the East Entrance road through Sylvan Pass to between the hours of 8:00 p.m. and 10:00 a.m.
