Castle Geyser

Description

The magnificent cone of Castle Geyser is thousands of years old and rests upon even older platforms. Together, they form one of the largest, and oldest, sinter formations in the world. Its eruption pattern has changed considerably throughout its recorded history. Castle is currently erupting about every 10 - 12 hours. A water eruption frequently reaches 90 feet (27m) and lasts about 20 minutes. The water phase is followed by a noisy steam phase lasting 30 - 40 minutes.
