A 60-year-old woman from New Hampshire suffered second and third-degree burns to her lower leg after falling into scalding water while hiking off-trail near Old Faithful in Yellowstone National Park. The incident occurred near the Mallard Lake Trailhead when she broke through a thin crust over a thermal area. She was initially treated at a park medical clinic before being flown to Eastern Idaho Regional Medical Center. Her husband and dog were not injured. Park officials reminded visitors to stay on designated trails and boardwalks in hydrothermal areas due to the fragile ground and scalding water just below the surface. This is the first reported thermal injury in the park this year.
