Abyss Pool is 53 feet (16 meters) deep and about 140 degrees Fahrenheit (60 degrees Celsius). In such springs, hot water cools as it reaches the surface and then sinks as it is replaced by hotter water from below. The circulation prevents the water from reaching the temperature needed to set off an eruption like those that happen in the park’s geysers.
Yellowstone spokesperson Morgan Warthin declined to provide more information about the incident, including what happened to the rest of Ro’s body or how investigators believe he died. She said a full report would be released in the coming weeks.
