From the latest issue of the Smithsonian:
Boiling Chickens in Yellowstone’s Hot Springs Is Illegal
“Some things should go without saying, but just to remind everyone: it’s definitely illegal to boil chickens in Yellowstone’s hot springs. But in August, three men learned this unspoken rule the hard way.
After being caught in the act by a park ranger, the trio pleaded guilty to a series of infractions that resulted in two years’ probation, during which time the men are banned from visiting the national park, and fines totaling between $500 and $1,200.”
The men said they double-wrapped the chickens in burlap to avoid contaminating the water, and “meant no disrespect” to the Park. Park personnel reminded the men that A) it is illegal to wander off the designated trails, and B) it is also illegal to put anything into the water, including tossing coins for “good luck”. It is very dangerous to walk near the thermal springs, as what can appear to be solid ground may only be a thin crust. In 2016 a young man left the designated boardwalk in the Norris Geyser Basin and subsequently broke through such a crust and fell into a scalding, highly acidic spring. The young person died and his body was never recovered.
The men may have avoided being boiled alive, but they definitely managed to cook their own goose.
