Otjikoto Lake
A round lake about 100 metres across, formed when the roof of a flooded cave collapsed.
A cave without a roof
Northern Namibia has a large area of dolomite with flooded caves below the surface. Otjikoto formed when the roof of one of these caves fell in. The walls are vertical, and the lake widens below the water line.
In 1915 German colonial troops threw rifles, ammunition and cannons into the lake before they surrendered to South African forces. Some pieces were later raised and are shown in the museum in Tsumeb.
