..Castle Geyser, Old

..Castle Geyser, Old Faithful area, Yellowstone National Park,WY, USA...the magnificent cone of Castle Geyser is thousands of years old and rests upon even older platforms. Together, they form one of the largest sinter formations in the world. Castle is currently erupting about every 14 hours. A water eruption reaches 75ft (24m), and lasts about 20 minutes, followed by a noisy steam phase of 30-40 minutes, Photo by Suchi-Deb..
