A group of tourists have been caught trying to take the temperature of a geyser at Yellowstone National Park by trespassing off the boardwalk and leaning over the hot water with a digital thermometer taped to a stick. The incident, a video of which which was shared via Instagram account TouronsOfYellowstone this week, took place at Minute Geyser, which once erupted every 60 seconds, but was 'killed' by careless tourists during the park's early days.
In the video, which you can watch below, the thermometer-carrying visitors can be seen wandering past a sign marked 'choked by ignorance', which refers to the geyser's sad history. Fascinated by the spouting hot water and not realizing the damage they were doing, early park visitors would throw coins and other items into Minute Geyser while waiting for stagecoaches.
