Pula e na haholo nakong ea lehlabula, ka linako tse ling e fihla ho 750 mm ka nako. Nakong ea linako tsa phetoho, lithemparetjha tse tlisoang le tse kopaneng li ka bolokoa bakeng sa linako tse fapaneng. Libaka tse ling li futhumetse ha tse ling li bata. Libakeng tse ling, hoetla ho na haholo.

Sebakeng se futhumetseng sa leholimo, matla a mocheso a fapanyetsana le libaka tse ling ho pholletsa le selemo. Hape, mouoane oa metsi o fallisoa ho tloha Leoatleng la Lefatše ho ea mobung. Ho na le matamo a mangata haholo ka har'a kontinenteng.
