At the surface Indian Spring seems like nothing impressive. Discharge of this spring is just 17 litres per second (the 7th magnitude) – nothing, if compared to nearby Wakulla Spring with its 11,000 litres per second.

Area around this spring is used for camping and spring itself is a fine place for swimming. Spring run – the stream above the land surface – continues for approximately 1 km and empties in Sally Ward Spring.

The underground stream

Spring contains a cavern – the part, which is reached by daylight and a cave – where natural light is not seen anymore.
Diving in this spring has revealed another – very exciting – reality. It turns out that below is a large, water-filled cave system with a powerful stream in it. Thus far the cave has been surveyed in 3,626 m length – going both upstreams and downstream from the entrance. The cave is up to 30 m deep.

The flow of the stream below the springs is thousands of liters per second. Although it has not been explored with certainty, this water most likely goes towards Wakulla Spring. Speed of stream is 0.1 m/s.

The explored passages of the Wakulla – Leon Sinks cave system are bypassing Indian Spring in a few hundred metres distance. Hydrological research shows that Indian Spring is connected to this cave system.

This category includes natural sites where water, other liquids and/or gases reach the surface of the Earth, including locations under water.

Powerful natural freshwater springs belong to the most fascinating monuments of nature. Even more exciting is the diversity of unusual springs – mineral springs, hot springs, submarine springs as well as the unusual black smokers. Especially beautiful are such natural rarities as travertine, silica or salt terraces created by warm and hot springs and, especially, geysers.
