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.

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.
In one of the last untamed places on Earth, Indonesian New Guinea’s snowcapped peaks tower above steaming rainforests and huge crocodiles stalk in thick mangroves ringing the island. Whether you lounge on the white beaches of Biak, or trek around Wamena, Indonesian New Guinea offers the adventure of a lifetime.
