Musfur sinkhole is located in Ar Rayyan, Qatar and it is the deepest known accessible cave in Qatar. The visible bottom is around 100 meter deep, but some scientists suspect a larger cave-system is extended below.
The sinkhole was formed 325,000 to 500,000 years ago during the mid-Pleistocene Era. When you enter the 40 feet opening of the cave you can see layering of different kinds of rock and sediments, graffiti on the rocks, hundreds of nesting birds and traces of small mammals. There is no clear path down into the cave. You can basically scramble down anywhere.
It is believed that Musfur sinkhole continues to evolve and will do so in the future. Pieces of rock from both the dolomite and limestone layers occasionally fall and larger sections of the roof might collapse one day.
