(AP) — Some tourists heading to Yellowstone National Park during the busy summer season are facing an hourlong detour Wednesday as a wildfire in neighboring Grand Teton National Park kept a highway closed. The fire in Grand Teton has burned about 11 square miles since lightning sparked it last month, forcing the evacuation of about 50 people from a lodge and cabin operation and several campgrounds. The largest blaze spans about 42 square miles between the community of West Yellowstone, Montana, and Madison Junction, an area in the park with a campground, visitor facilities and staff housing. Cooler temperatures and higher humidity were expected over the next couple of days and should help firefighters, Miranda said.
