One of my favorite Yellowstone idiot deaths:

On June 7, 2016, Colin Nathaniel Scott, a 23-year-old American man from Portland, Oregon, died after falling into a thermal hot spring in Yellowstone National Park. The incident occurred in the Norris Geyser Basin, an area known for its geothermal features, including acidic and high-temperature hot springs. Scott and his sister, Sable Scott, had deviated from the designated boardwalk area and entered a restricted section of the park. Reports indicate that they intended to partake in "hot potting," the prohibited activity of bathing in Yellowstone's thermal pools.
When park officials arrived at the scene, they initially found partial remains, including Scott's head, upper torso, and hands.[1] However, the extreme heat of the spring, which had reached 100 °C (212 °F), along with an incoming lightning storm, prevented immediate recovery. By the following day, the acidic water had dissolved his body, leaving only a few personal belongings, such as his wallet and flip-flops.
Boiled to death in acid. What a way to go.
