But park regulations allow swimming in many places where hot water meets a cold water stream — like where the Boiling River meets the Gardner. The swimming hole is located within the park between the North Entrance at Gardiner and Mammoth Hot Springs.
Longtime locals swimming at Boiling River on Feb. 22 told Livingston Enterprise Managing Editor Justin Post the water seemed hotter than they've ever remembered it. A small cascade of hot water which in the past has been pleasant to sit under was unapproachably hot one recent Sunday, Post said.
Heasler, who has been with the park for about 12 years, said he and his staff aren't absolutely certain what's going on, but they are examining a couple of theories.

Perhaps a "cork" effect happens on extreme winters? Water volume expands about 10% during the freezing to ice process jamming in rock fissures, crevasses.
A long drive to the Condo hot tub for cooler water!
One theory is cold water flowing into the Boiling River through underground sinkholes in the underlying travertine is being blocked or diverted somehow.
A test of the hypothesis happened by accident last summer when water flowing into a sinkhole was temporarily diverted while park staff addressed a small area of invasive plants.
While that water was diverted, the temperature of Boiling River increased, Heasler told the Livingston Enterprise (http://(link tracking not allowed)/1BquuPK ).
Heasler had another confirmation of this theory in January. On one of the coldest days of the winter, the Boiling River temperature climbed to 140 degrees.
"I went and looked, and the sinkhole had frozen over," Heasler said.

I'm not sure if its a good or bad thing that I live in the vicinity of Yellowstone. I'm sure the initial blast and shock wave would be devastating.
