YELLOWSTONE NATIONAL PARK, Wyo. (AP) — The South Entrance to Yellowstone National Park is expected to remain closed this weekend because of a wildfire in Grand Teton where firefighters are trying to clean up hotspots and burned trees along a 2-mile stretch of highway. The closure of U.S. 89/191/287 that leads into Yellowstone is forcing some park visitors to take an hour-long detour. Grand Teton fire spokesman David Eaker (A-ker) said Saturday that firefighters are focusing on the highway.
