Kustelyarovsky Hydrogen Sulfide Spring
It is referred to warm springs with the constant temperature of +18-20 degrees Centigrade. The spring brings out a powerful jet of mineralized water with the speed of 20l/sec. from the terrace over the flood-land of the Yuruzan River. Larger gas bubbles 2-3 sm. in diameter make up garlands of crystal balls that sparkle I the spring and burst when they reach the surface. The spring's waters contain gases of hydrogen sulfide, hydrocarbons, nitrogen, argon and helium. A lot of organic medicinal mud is accumulated near the spring's outlet.
