>>> among visitors to yellowstone national park it is the holy grail , the steamboat geyser , not as famous as old faithful. not faithful at all, in fact. steamboat has a funny way of deciding for itself when to let off steam. and it just did for the first time in eight years. a few folks caught the rare eruption, well some caught it right side up on wednesday. it was a huge thrill at the height of the summer tourist season . it lasted nine minutes. when this goes off, steamboat is taller than old faithful. up to 300 feet in the air. it is very fickle though. back in 1964 , it went off 29 times in a year. while it was once also silent for 50 years at a time.
