Rising like the grey-colored humps of hippo wallowing in muddy water,Kubu Island is a fitting name for the mounds of rock that lie almost smack bang in the middle of Botswana’s Makgadikgadi Salt Pans. "Kubu" is the local Setswana word for hippopotamus and besides describing the island’s physical characteristics, the local lingo for this current off-roading destination also alludes to its surprising watery history.
Although the rocky outcrop is roughly 30 feet high, and the summit of Kubu Island is enough to offer panoramic views across the huge plains surrounding it. Turn in a 360-degree circle and you cannot see any other civilization,only an infinite white horizon. This total lack of human habitation also makes this grand white space a top location for uninterrupted stargazing. Geologically speaking, these sprawling salt flats bear proof that this was once a prehistoric lake. The water that now feeds the Okavango Delta, or all the way from Angola in the north used to spill over here,but tectonic activity shifted the waters absent leaving today's travelers with the only desert. Look closely at some of the seemingly whitewashed rocks. Experts say this is actually fossilized guano from waterbirds that once perched along the edge of the grand Makgadigadi Lake.
