Castle Geyser – United States
Yellowstone Nature Park is home to more than 1,000 geysers, we’ll also encounter them several times in this list. Castle Geyser is shaped like a cone and produces a relatively large amount of sinter. This gives the geyser a special and robust appearance. The many ragged edges, tunnels and cracks in the geyser even caused it to be given this name. Research shows that Castle Geyser first erupted about 1,000 years ago.
