Te Kopia Mud Geyser
Unusual and a fairly spectacular mud geyser. During the periods of activity every 10-30 minutes, it ejects a muddy fountain that is some 3-10 m tall.
Mokena Geyser
Artificial geyser – a hot soda spring that erupts every 30 – 40 minutes and is up to 4 m high.
Warm Mineral Springs
Enormous spring of warm mineral water with healing properties. This is one of the candidates for the legendary “Fountain of Youth” in Florida. The diameter of this spring is approximately 75 m, depth – 70 m. Discharging 390 l/s and considered to be the largest warm mineral spring in the whole world. In the spring have been found well preserved skeletal remains of humans, mastodon, sabertooth tiger.
De Leon Springs
Large sulfur spring, discharging 880 l/s of water. Surroundings inhabited since 8000 BC.
Montezuma Well
Large sinkhole, 112 m wide and 17 m deep. It is fed by powerful springs and its water has a high level of dissolved arsenic. In the sinkhole live at least five endemic organisms.
Paralana Radioactive Springs
Hot springs with a temperature of 57 degrees C, highly radioactive. The heat could be caused by the natural nuclear fission. Discharge – 16 l/s.
Kalarskiy Geyser
Kalarskiy Geyser is a small geyser, or, rather intermittent thermal spring in remote, beautiful area of Siberia. Fountain is some 0.2 – 0.5 m high.

Dallol hot springs and geysers
One of the visually most outstanding places on Earth, the hot springs have a high salt concentration that has shaped terraces and other formations of very bright, unusual colors. Among the hot springs, there is also a salt geyser – possibly the only one in the world.
