YELLOWSTONE NATIONAL PARK - Crews are fighting a new wildfire Wednesday evening in the southwest corner of Yellowstone National Park. The Ash fire in the Bechler area was detected by Yellowstone helitack crew on an aerial reconnaissance mission, park officials said in a news release. The fire was estimated at 10 acres on Wednesday night.

A teenage boy visiting Yellowstone National Park was seriously burned when his foot broke through the ground near a geyser by the infamous Old Faithful, officials said.

The teenager, a 17-year-old boy, was hiking on Monday in the thermal area near the Lone Star Geyser, which is in the same geyser basin as Old Faithful, when his foot broke through the crust, causing “significant thermal burns to his foot and ankle area,” the park service said in a statement.
