The water in the springs originates from a fault in the limestone plateau, and the mechanics of piping pseudokarst draw hot water from nearly 2,000 m (6,600 ft) deep in the earth upwards through the fault.
The water emerges in a central pool at the top of the mound and flows downward through a terrace of surrounding pools. The travertine walls of these pools can be as tall as 30 cm (12 in), and range in colour from grey to off-white. The spring water is rich in dissolved minerals from the limestone, such as calcium carbonate. These minerals are deposited on any surface the water flows over, gradually coating it and forming tufa structures known as rimstone dams and gours. Eventually, the older pools begin to fill with deposited minerals, which causes the water to spill over the edges and form new pools.
Due to the fragile nature of the tufa structures, tourists are only permitted to visit the hot springs with guided tours run by park staff. Visitors must remove their shoes and walk barefoot on a prescribed path to get close to the North Mound.
