If temperatures rise 10F by the century’s end as projected, Old Faithful could stop erupting, and the snowpack that feeds rivers throughout the west may disappear
When a band of geological surveyors and US army scouts mapped out what would become Yellowstone in 1870, the geysers and springs seemed endless – a land so unbound that Congress moved to name it the world’s first national park.
Nearly 150 years later, about 4 million people visit the park annually to see its most famous geyser: Old Faithful. It is a sight to behold, shooting tens of thousands of litres of boiling water hundreds of feet into the air about 17 times a day.
