Old Faithful
This image was taken near the end of an eruption and shows more steam than water.
Old Faithful is one of nearly 500 geysers in Yellowstone and one of six that park rangers can currently predict. The intervals between eruptions vary from 50 to 110 minutes on average, but that doesn’t make the famous geyser less predictable. The length of an eruption impacts the interval between eruptions, helping park rangers know when to expect them. In the 1960s, the average interval between eruptions was 66 minutes, quite a bit shorter than today’s 91 minutes. The change may result from earthquake activity, changes to the water table, climate change, or human activities like water diversion and construction projects.
Thanks for stopping by and for all of your kind comments, awards and faves -- I appreciate them all.
