Tekro
Tekro is a well in the desert northeast of the Ounianga lakes, near a salt deposit mixed with sand. Its relatively fresh water lies on the southern approach to the Libyan Desert and the distant oasis of Kufra. Around the well, sparse siwak bushes and a little grass offer scant grazing for camels. To the west, the Arouelli salt flats supplied caravans travelling towards Wadai; farther south, groundwater sustains the lakes of Ounianga amid the surrounding sandstone desert.
