Kef Toghobeit Cave
Kef Toghobeit is a karst cave near the settlement of Bab Taza in Chefchaouen Province, Tanger-Tetouan-Al Hoceima, in northern Morocco. Currently known to be long and deep, it is the deepest cave in Morocco, and the third deepest cave in Africa.
Although Kef Toghobeit has been well-explored, its full extent is not yet known. Indeed, the karst topography of the Rif mountain range where the cave begins has barely been mapped - just 1000 caves are known in Morocco, and the geology would suggest that more than this exist.
Actun Box Ch'iich'
At -183m, Actun Box Ch'iich' (Cave of the Black Birds) is the deepest cave in the country of Belize. Located above Roaring Creek in the Cayo District, it is one of several caves explored and documented by British and Canadian cavers during a three-week expedition in 1989. The cave contains a small stream and has both an upper and lower entrance, making a through-trip possible.
