The Berry Fire burns off the shore of Jackson Lake in Grand Teton National Park, Wyo., Thursday, Aug 25, 2016. Popular areas in Yellowstone and Grand Teton National Parks were welcoming tourists Thursday for the 100th anniversary of the National Park Service, but a wildfire forced some people to drive a little farther than they expected. The blaze in Grand Teton National Park shut down a route leading to Yellowstone's South Entrance, so visitors coming from the south through Wyoming had to take a detour into Idaho.
