Iguazu Falls feet, are a third shorter). Often, Iguazu also is compared with Victoria Falls in Southern Africa, which separates Zambia and Zimbabwe. Iguazu is wider, but because it is split into roughly 275 distinct falls and large islands, Victoria has the largest curtain of water in the world, at more than wide and over in height (in low flow, Victoria is split into five by islands; in high flow it may be uninterrupted). The only wider falls are extremely large rapid-like falls, such as the Boyoma Falls (Stanley Falls). With the flooding of the Guaíra Falls in 1982, Iguazu currently has
Victoria Falls line and abandonment of the earlier line. North-south oriented joints control the south flowing sections of the river. One of these is the "Boiling Pot", which links the First Gorge with the Second Gorge. The falls may have already started cutting back the next major gorge, at the dip in one side of the "Devil's Cataract", between the western river bank and Cataract Island. The lip in the current falls is lowest here and carries the greatest concentration of water at flood stage. The sedimentary sequence overlying the basalt at the Zambezi River margins is called the Victoria Falls Formation,
