The basin and parking lot were temporarily closed but have since reopened, according to Warthin. Park officials have ruled out foul play, the National Park Service said in a news release Friday, and point to a possible death last month. “The evidence from the investigation so far suggests that a one-person incident likely occurred on the morning of July 31, 2022 at Abyss Pool,” the statement said. Investigators are still working to determine the circumstances surrounding the death, officials said. Abyss Pool is up to 53 feet deep, according to the National Park Service. It has a temperature of about 140 degrees Fahrenheit (60 degrees Celsius), Warthin said. The water in these hot springs can “severely burn” visitors, the agency warns on its website.
