Spectacular scenery at an altitude of 30.000 feet from left window of the aircraft Surabaya-Denpasar evokes a question about the location of a green Tosca lake at an altitude of 2.000 feet. The lake looks like inside the crater with caldera wall as high as 300-500m. A towering mountain peaks located beside it. White smoke billowing from one of its crater, soaring into the air making the contrast with the surroundings which are green jade. The crater is Ijen crater, which is located in Banyuwangi, East Java. The spot has been ever published and well known in France by Ushuwaia Adventure show which shows Nicolai Hulot the explorer , sitting on a rubber boat telling about the origin of the lake of Ijen with zero degrees of acidity, has a depth of 200 meters.
Acidity is strong enough to dissolve the clothes and fingers. Bird view of the helicopter's camera view then switched to the edge of the caldera which showed the Ijen crater miners struggling to climb carrying dozens of kilograms of their load. Ijen crater is easy to visit via Banyuwangi or Bondowoso. The main uniqueness of Ijen crater is not only on a beautiful panoramic view but also on traditional sulfuris mining carried by human power. Traditional mining is said to be only found in Indonesia (Welirang and Ijen). The Load transported each weighing up to 85kg per person.
