In detail
This deep sinkhole in the Arfak Mountains was formed when the ceiling of a cave above the Aouk Underground River collapsed. This hole is some 150 m long and 110 m wide, approximately 160 – 180 m deep. The sinkhole is bell-shaped – below it is wider, but its mouth above is more narrow – just 100 by 60 m wide. Its volume is approximately 1.4 million m3.
The size of this sinkhole exceeds 100 m and also the depth exceeds 100 m – thus Keek sinkhole can be considered to be a true tiankeng.
The whole floor of this sinkhole is just a fast river – this hole in the ground is a window to the underground stream of Aouk. The stream of Aouk comes from the south after passing through some 1.7 km long underground passage from Wakut – the gloomy entrance in Aouk Underground River.
Nearby are two more giant sinkholes: Hafasu Tiankeng and Kuom Tiankeng.

Wonders of Indonesia
Indonesia is a true land of wonders. There are few other countries in the world that can offer a similar array of diverse, unique, and beautiful natural and cultural monuments.
Sinkholes
This category includes outstanding sinkholes – large natural depressions or holes, which for most the part represent collapsed caves.
Wonders of Asia
Any other continent (and part of the world) seems small if compared to Asia. This refers also to natural and man-made heritage: in Asia are not just thousands of great landmarks, there are found landmarks created by thousands of diverse cultures from ancient Phoenicians to the mysterious small people in the Philippines and eastern islands of Indonesia.

Caves
Bit by bit, over thousands or even millions of years, water carves and shapes rock into designs only nature could create. Deep in limestone or under a few feet of hardened lava, on an ocean coast or a sandstone cliff, a cave is a mysterious and fascinating place.
