Musfer Sinkhole is the official name of a karst cave in Umm Al Shabrum, central Qatar. This sinkhole is one of the karst features. Other karst features include depressions, caves, and solution hollows. Karst is a distinctive environment characterized by landforms that are the product of dissolution of surface and subsurface rock by natural water to a greater extent than in other landscapes. It occurs both as surface and underground features. Several substantial caves are known in Qatar, but many have probably been filled with blown sand, or have collapsed to produce some of the thousands of depressions or dolines.
It wasn't too difficult to find the cave. The opening isn't that big but it's surrounded by a fence which made it clear.
Inside was mostly limestone as that's what Qatar is predominantly made up of. We did find a bit of gypsum.
It goes quite deep!
Nearby we passed this old police station for Um Al-Shobrum.
