Grading - 225405

The sandstone is 200 metres wide and up to 4 metres thick and has a well-exposed channel bank on the northern side. The channel is filled with five vertically-stacked sandstone lenses and is capped with overstepping "wing" sandstones up to one metre thick. It has been interpreted as a distributary or crevasse channel-fill deposit, which incised into coherent mud of a floodplain origin. Fossilised skeletons of therapsid or mammal-like reptiles support a terrestrial environment. The mudstone-dominated succession in Teekloof Pass forms the Hoedemaker Member of the Teekloof Formation. The underlying sandstone-rich Poortjie Member occurs near the base of the pass and the overlying sandstone-rich Oukloof Member caps the pass some 2 km to the north.
