Tourists at Yellowstone National Park

Old Faithful, located in Yellowstone National Park, is one seriously powerful geyser. During one of its regular eruptions, the geyser spews some 3,700 gallons of water up to 184 feet in the air. During that event, the water comes out at about 204 degrees Fahrenheit with steam temperatures up to 350 degrees. So yes, it’s dangerous. But that fact didn’t stop one ill-informed tourist from attempting to stand next to Old Faithful as it erupted.

On Saturday, a horrified onlooker shot and shared a video of a male tourist approaching the geyser just as it was expected to blow.

“Shameful behavior at Yellowstone this morning,” park attendee Devin Bartolotta tweeted. “While hundreds of people waited for Old Faithful to go off, some guy shamelessly walked within feet of the geyser to take a picture, then flipped off the boo-ing crowd. Park staff has his photo and followed him until rangers arrived.”

According to Bartolla, who spoke to a local NBC affiliate, the man got within 20 to 30 feet of the geyser before he stopped, pulled out his cell phone, and took a picture.

"That's when everyone realized that he was not a ranger. The whole crowd started booing,” she explained. “He was well within the danger zone of this being a potential life threatening situation because it could have gone off at anytime. If that had started to gurgle and spit a little bit before he walked up there. So it really could have been a really bad situation if he had been a second or two in the wrong time."

No word on what happened to the man after park rangers followed him out, but as Fox noted, the man is just lucky to be alive.

“Hot springs have injured or killed more people in Yellowstone than any other natural feature,” according to NPS’s online warning. “Keep your children close and don’t let them run.”
