The name means 'muddy lake,' and the water looks the part - sometimes reddish, reportedly a little oily, often more mud than lake. Mweru Wantipa, sometimes called Mweru Marsh, is a rift-valley lake in Zambia's Northern Province that has done something most lakes do not: it has repeatedly stopped being one. Reports describe it as a lake in 1890, 1897, 1911, 1919, and 1938, but a swamp in 1892 and most years between 1900 and 1922. Around 1916 it dried out almost entirely into a plain of caked mud littered with fish scales, hippo bones, and crocodile skeletons. Then it filled back up.
