Old Faithful, named by members of the 1870 Washburn Expedition, was once called “Eternity’s Timepiece” because of the regularity of its eruptions. Despite the myth, this geyser has never erupted at exact hourly intervals, nor is it the largest or most regular geyser in Yellowstone National Park. It does, however, erupt more frequently than any other of the large geysers.
Это гейзер "Старый служака", выбрасывает фонтан горячей воды и пара. Периодически, вот картинка из вики:
А когда же он перестаёт фонтанировать? Уже 4-й день смотрю.
