A 26-year-old woman from Connecticut who walked directly on thermal features in Yellowstone National Park (US) in July was sentenced to a week in jail. The woman, Madeline S. Casey, and another person, made their way to a thermal ground despite nearby signs asking visitors to stay on the boardwalk. “The ground is thin and the water below can cause serious or deadly burns,” said Morgan Warthin, a Yellowstone National Park spokeswoman. Casey will be paying a total of $2,040 in fines, fees, and community service. She has until the end of January 2022 to complete her jail time and make the community service payment. The officers have been asking visitors to follow the safety signs at the national park. In May 2020, a woman suffered burns after falling into a thermal feature at Yellowstone. She told officers that she fell after taking pictures. “Visitors should know that walking on thermal features is dangerous and not allowed.” Park Chief Ranger Sarah Davis said in a statement.
