According to the park ranger who took the call the "thermal feature" he fell into was a fucking MUDPOT that was superheated (beyond the thermometer's range she says). She said it was approx 12ft deep (deeper than it was wide) and that it isn't a main/known feature and does not have a name.
Clearly he wasn't going in for a swim, unless he felt like lolling in a fucking boiling mudpot.
>pic is a shitty mudpot pic I took in Jellystone a few years agoThat thing was fucking viscious.
