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 4,078 m (13,379 ft) long and 722 m (2,369 ft) deep, it is the deepest cave in Morocco, and the third deepest cave in Africa.[1][2] Although Kef Toghobeit has been well-explored, its full extent is not yet known.[3] 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.[1]

Topography and formation

Kef Toghobeit is just one of over a thousand caves in a 30,000 square kilometre area of Karst formation in Morocco.[1] The cave formed in the Rif mountain range, which is primarily formed of relatively soft minerals such as dolomite and limestone.[1] Winter snowfall and rainfall add up to an annual precipitation rate of 600 to 1000 mm. The heavy precipitation quickly erodes the soft minerals, creating deep caves where the water wore away at the stone.

The interior of Kef Toghobeit is covered in loose boulders and rubble.[4]

gollark: Also, they can't emit IR and cook me, *or* emit (much) RF and probably somewhat break electronic stuff.
gollark: Obviously we need monitors which can properly represent laser videos, by blinding oyu.
gollark: To be able to emit ionizing radiation, yes.
gollark: Most monitors can't even generate a lot of *visible* spectrum colors, even. There are a bunch of color space diagrams of this on the internet, except they're not a very good way to show it because, unsurprisingly, the cyan-ish bit they can't display well just looks like identical cyan.
gollark: That would just allow per-*column* control, unless you scan them left and right really fast.
