This area is rich with karst features – here are known more than 50 caves, often adorned with amazing speleothems. In Wamena karst are found several giant sinkholes as well, reaching up to the size of tiankeng (a giant sinkhole, at least 100 m deep and wide).
Yogoluk Sinkhole has formed by the collapse of a roof of giant cave room – in image is seen how the cave continues – or there is even a giant natural arch (see this image from Commissione Grotte Eugenio Boegan) to one side. On the floor of this sinkhole there still is approximately 80 m high pile of debris.
Yogoluk Sinkhole has approximately 180 m wide and long opening with area 25 000 m2. Depth of sinkhole is 230 – 240 m, volume – 4 million m³.

Indonesia is a true land of wonders. There are few other countries in the world which can offer similar array of diverse, unique and beautiful natural and cultural monuments.
Category includes outstanding sinkholes – large natural depressions or holes, which for most part represent collapsed caves.
Indonesia is the fabled “Spice Islands” of every school child’s dreams—one of the most colorful and fascinating countries in history. These are the islands that Europeans set out on countless voyages of discovery to find and later fought bitterly over in the 15th, 16th and 17th centuries.
On November 21, 1961, Michael C. Rockefeller, the twenty-three-year-old son of New York governor Nelson Rockefeller, vanished off the coast of southwest New Guinea when his boat capsized. He was on a collecting expedition for the Museum of Primitive Art, and his partner—who stayed with the boat and was later rescued—shared Michael’s final words as he swam for help: “I think I can make it.”
