Jumping Frogs Mud Pool Rotorua.
This pool is known as "the frog pool" as many believe the mud resembles leaping frogs in a pond.
Mud pools are created when hydrogen sulphide is released into the air, reacting with oxygen and creating sulphuric acid. This acid has the ability to dissolve rock into fine particles of silica and clay, which is called kaolin. Kaolin is white when pure, but finely black sulphur in the mud pool turns it grey.
