…the most famous Geyser in the world. Discovered in 1870 by the Washburn Expedition, Old Faithful geyser was named for its frequent eruptions — which number more than a million since Yellowstone became the world’s first national park in 1872.
Old Faithful can vary in height from 106-184 feet (32–56 m) with an average near 130 feet (40 m). This has been the historical range of its recorded height. Eruptions normally last between 1.5 to 5 minutes.
During an eruption, the water temperature at the vent has been measured at 204°F (95.6C). The steam temperature has been measured above 350°.
Old Faithful’s eruptions vary from 60 to 110 minutes.
Old Faithful has a faithful following of people who will sit and wait to see it erupt. We saw one other very impressive geyser not too far from Old Faithful in the distance while we were waiting for Old Faithful and then again on our morning walk the next day.
I zoomed in to get these shots and it looks as if the people are being enveloped
This was such a new and interesting experience for us. On our morning walk we were very close to this second geyser when it erupted and I’ll show more photos of it in another post.
Today is Thursday. Dear has been working on a new yard project and if the rain holds off he’ll finish up today. Our kids will complete their move this weekend after our daughter’s last day in her present job on Friday. She’ll be happily unemployed until the Fall.
