Today the main focus of our visit to YNP was to see ‘Old Faithful’ which is a cone geyser. It is called the most predictable geographical feature on Earth erupting almost every 91 minutes and each eruption can last from 1.5 to 5 minutes. The average height of an eruption is 145 feet (44 metres) with the highest recorded eruption being 185 feet (56 metres). It is the most viewed geyser in the Park and each time Old Faithful erupts there are hundreds of people there to record the event.
We also went to have a look at Grand Prismatic Spring. It is the largest hot spring in the United States and the third largest in the world The lake is known for its turquoise colour and so our ‘resident photographer’ was rather disappointed not to be able to see it due to the rising steam.
The vivid colors in the spring are the result of pigmented bacteria in the microbial mats that grow around the edges of the mineral-rich water
As you travel round the Park, Yellowstone has so many different faces, meadows, mountains, rivers, streams, lakes, canyons and rolling hills it’s no wonder that it was made the first National Park. It covers over two million acres!!
We were lucky today to see a Buffalo treading the highway and a big buck Elk with his harem, they decided to spend the afternoon sitting outside the Mammoth Hot Springs Hotel.
The last picture is of a small lake we pass when we drive down the mountain ….. we’ve christened it ‘the fishing hole’.
