Old Faithful Erupting

I said earlier that we had to wait about ninety minutes until we were able to witness an erupting of the most famous geyser in Yellowstone National Park, Old Faithful. It a cone geyser, which got its name already in 1870, the first in the park to receive a name. The name reflects the fact that the eruptions are highly predictable with intervals ranging between 60 and 110 minutes (90 minutes on average, depending on the size of the previous eruption). At an eruption, between 14,000 and 32,000 litres of boiling water are shot into the air to a height of 32 to 56 metres. This last from 1.5 to 5 minutes. More than 1,000,000 eruptions have been recorded.

Here are three photos taken of the eruption we witnessed. Even though I like the big white clouds, they are not the perfect backdrop for the geyser eruption.
