Izicucu zokuqala ezilandelanayo ezabekeka ngaphezu koqwembe olusha kwaba i-Natal Group yesikhathi se-Cambrian kuya kwi-Ordovician izigidi ezingamakhulu amane namashumi ayisishiya galolunye yeminyaka edlule.
Izimo ezigcinekile kulama-sandstone zikhomba ukuthi izicucu zathuthwa futhi zabekwa imifula eyomisa ezindaweni eziphakeme nenyakatho ngasempumalanga. Maduze neziqalo, enyakatho neKZN, izigodi ezijulile zagcwaliswa izimbokodo ezazinohlonze. Ezansi neningizimu izicucu zicoyisakele zincane, zakha amawa e-sandstone aqinile.
Lokhu kuvela kubonakale njengengaphezu kwetafula (kuqondile phezulu) ezindaweni ezifana ne-Valley of a Thousand Hills, Oribi Gorge eduze ne-Port Shepstone.

Typically pinkish-coloured, these sandstones are medium-grained (sand grains are visible to the naked eye) and may be seen as table-top mountains with cliffs having very clear layers known as bedding. The sand was deposited in a river environment and ripple marks may be seen in large rock outcrops.
