Billions of thermoacidophiles live in these waters which are 10 times more acidic than lemon juice and almost as much as battery acid. They convert the pool's hydrogen sulfide gas into sulfuric acid which breaks soil and rock into mud.

The center of the pool has a vibrant, clear blue color, which gradually fades into lighter shades near the edges. Steam gently rises from the water, adding to the atmosphere of warmth and activity beneath the surface. The surrounding ground is textured with mineral deposits and colors, including orange and yellow hues, which suggest the presence of thermophilic microorganisms. The edges of the pool are rimmed with white mineral formations, creating a stark contrast with the deep blue water.
